Can someone tell the relationship between the words ergonomics and bionics?

@sachigre thanks for the explanations, for the last question even i have come up with the same answer but the answer for last one was given as 'a' :hmm:

Word order in a sentence was much freer in Old French than it is in French today; this ------- disappeared as the French language gradually lost its case distinctions. (A) restriction (B) license © similarity (D) rigidity (E) imperative Whereas biologists must maintain a ------- attitude toward the subjects of their research, social scientists must, paradoxically, combine personal involvement and scholarly -------. (A) scrupulous. .sympathy (B) careful. .abandon © casual. .precision (D) passive. .passion (E) disinterested. .detachment An obvious style, easily identified by some superficial quirk, is properly ------- as a mere mannerism, whereas a complex and subtle style ------- reduction to a formula. (A) avoided. .risks (B) decried. .resists © prized. .withstands (D) identified. .consists of (E) cultivated. .demands

mantrapad!! Thanks for such a comprehensive explanation...:tup:

@Ndure and Espinosa88 thanks...

Bracken fern has been spreading from its woodland strongholds for centuries, but the rate of encroachment into open countryside has lately increased alarmingly through- Line out northern and western Britain. A tough competitor, (5) bracken reduces the value of grazing land by crowding out other vegetation. The fern is itself poisonous to livestock, and also encourages proliferation of sheep ticks, which not only attack sheep but also transmit diseases. No less important to some people are bracken's effects on threatened (10) habitats and on the use of uplands for recreational purposes, even though many appreciate its beauty. Biological controls may be the only economic solution. One potentially cheap and self-sustaining method of halting the spread of bracken is to introduce natural enemies of the (15) plant. Initially unrestrained by predators of their own, foreign predators are likely to be able to multiply rapidly and overwhelm intended targets. Because bracken occurs throughout the world, there is plenty of scope for this approach. Two candidates, both moths from the Southern (20) Hemisphere, are now being studied. Of course, biological control agents can safely be released only if it can be verified that they feed solely on the target weed. The screening tests have so far been fraught with difficulties. The first large shipment of moths (25) succumbed to a disease. Growing enough bracken indoors is difficult, and the moths do not readily exploit cut stems. These are common problems with rearing insects for biological control. Other problems can be foreseen. Policymakers need to (30) consider many factors and opinions such as the cost of control compared to existing methods, and the impact of the clearance of bracken on the landscape, wildlife, and vegetation. In fact, scientists already have much of the information needed to assess the impact of biological (35) control of bracken, but it is spread among many individuals, organizations, and government bodies. The potential gains for the environment are likely to outweigh the losses because few plants, insects, mammals, and birds live associated only with bracken, and many would benefit (40) from a return of other vegetation or from a more diverse mosaic of habitats. But legal consequences of attempts at biological control present a potential minefield. For example, many rural tenants still have the right of "estovers"— the right to cut bracken as bedding for livestock and other (45) uses. What would happen if they were deprived of these rights? Once a biological control agent is released, it is difficult to control its spread. What consideration is due landowners who do not want to control bracken? According to law, the release of biological control agents must be (50) authorized by the secretary of state for the environment. But Britain lacks the legal and administrative machinery to assemble evidence for and against release. As it is discussed in the passage, the place of bracken within the forest habitat can best be described as (A) rapidly expanding (B) the subject of controversy © well established (D) circumscribed by numerous predators (E) a significant nutrient source I gave answer 'A' but it is can someone hightlight the text how xxx can be the answer.

@cwnelatury thanks, awesome explanation. You have pointed exactly where i went wrong. Good explanation.

agreed with you guys even i felt it was unilluminating @anxiteyx0 good to know that there are some errors in real 19..thanks...

Hey guys!! thanks for explanation..

thanks sachigre, good explanation indeed.

CRAVEN : ADMIRABLE :: (A) unruly : energetic (B) listless : attractive © deft : awkward (D) trifling : amusing (E) volatile : passionate A person who is craven is not admirable A person who is deft is not awkward A person who is volatile is not passionate I have chosen e but the answer is

please explain.. FEED : HUNGER :: (A) reassure : uneasiness (B) penetrate : inclusion © abandon : desolation (D) transfer : location (E) fertilize : growth

@neel39, thanks for keeping it simple and helping me to understand.[clap] still, i have some problem with the 1st sentence, i tried to understand it. but i couldn't. can you please tell the answer for this 1====> The proper use of figurative language must be based on the denotative meaning of the words, because it is the failure to recognize this ------- meaning that leads to mixed metaphors and their attendant incongruity. (A) esoteric (B) literal © latent (D) allusive (E) symbolic and then for this 2==> Ironically, the proper use of figurative language must be based on the denotative meaning of the words, because it is the failure to recognize this ------- meaning that leads to mixed metaphors and their attendant incongruity. (A) esoteric (B) literal © latent (D) allusive (E) symbolic what is the function of ironically in the second one. plz someone explain..

Hey Ndure!! even i know the answers. what i need is explanation.please, someone explain my doubts.

I think it is C ,if it is C i can try to explain you. But, first please let me know the answer.

1====> The proper use of figurative language must be based on the denotative meaning of the words, because it is the failure to recognize this ------- meaning that leads to mixed metaphors and their attendant incongruity. (A) esoteric (B) literal © latent (D) allusive (E) symbolic For this the answer looks to be like 'B' right?? Ironically, the proper use of figurative language must be based on the denotative meaning of the words, because it is the failure to recognize this ------- meaning that leads to mixed metaphors and their attendant incongruity. (A) esoteric (B) literal © latent (D) allusive (E) symbolic This is the actual question, what difference does it make to the answer. I heard that if ironically is present in a question we should keep the answer opposite to what we are expecting. so, i have blindly marked the answer as allusive(opp of literal..) but, the answer is literal. Please, explain me how ironically functions in this question. 2===> Although frequent air travelers remain unconvinced, researchers have found that, paradoxically, the ------ disorientation inherent in jet lag also may yield some mental health -------. (A) temporal. .benefits (B) acquired. .hazards © somatic. .disorders (D) random. .deficiencies (E) typical. .standards By looking at the first part of the above SC you would expect second part of the sentence to convey the meaning that they are convinced. as "frequent" is mentioned in the above SC it is quite believable that they are unconvinced that something bad can happen. so i have arrived at 'a' and 'e'. Inherent suggests that it is an in built quality, so it has to be typical(some thing most common). I was shocked to see the answer to be 'A' thought its second blank conveys the meaning well the first answer doesnt fit in.

HI cwnelatury, The answer is indeed 'c' i have marked it as 'd'. It looks more like d for me.can you explain the answer by highlighting the sentences which made you to come to this answer.

About a century ago, the Swedish physical scientist Arrhenius proposed a law of classical chemistry that relates chemical reaction rate to temperature. According Lineto the Arrhenius equation, chemical reactions are (5) increasingly unlikely to occur as temperatures approach absolute zero, and at absolute zero (zero degrees Kelvin, or minus 273 degrees Celsius) reactions stop. However, recent experimental evidence reveals that although the Arrhenius equation is generally accurate in describing (10) the kind of chemical reaction that occurs at relatively high temperatures, at temperatures closer to zero a quantum-mechanical effect known as tunneling comes into play; this effect accounts for chemical reactions that are forbidden by the principles of classical chemistry. (15) Specifically, entire molecules can "tunnel" through the barriers of repulsive forces from other molecules and chemically react even though these molecules do not have sufficient energy, according to classical chemistry to overcome the repulsive barrier. (20) The rate of any chemical reaction, regardless of the temperature at which it takes place, usually depends on a very important characteristic known as its activation energy. Any molecule can be imagined to reside at the bottom of a so-called potential well of energy. (25) A chemical reaction corresponds to the transition of a molecule from the bottom of one potential well to the bottom of another. In classical chemistry such a transition can be accomplished only by going over the potential barrier between the wells, the height of which (30) remains constant and is called the activation energy of the reaction. In tunneling, the reacting molecules tunnel from the bottom of one to the bottom of another well without having to rise over the barrier between the two wells. Recently researchers have developed the concept (35) of tunneling temperature: the temperature below which tunneling transitions greatly outnumber Arrhenius transitions, and classical mechanics gives way to its quantum counterpart. This tunneling phenomenon at very low temperatures (40) suggested my hypothesis about a cold prehistory of life: the connation of rather complex organic molecules in the deep cold of outer space, where temperatures usually reach only a few degrees Kelvin. Cosmic rays (high energy protons and other particles) might trigger the (45) synthesis of simple molecules, such as interstellar formaldehyde, in dark clouds of interstellar dust Afterward complex organic molecules would be formed, slowly but surely, by means of tunneling. After I offered my hypothesis, Hoyle and Wickramasinghe argued that (50) molecules of interstellar formaldehyde have indeed evolved into stable polysaccharides such as cellulose and starch. Their conclusions, although strongly disputed, have generated excitement among investigators such as myself who are proposing that the galactic clouds are the (55) places where the prebiological evolution of compounds necessary to life occurred. The author's attitude toward the theory of a cold prehistory of life can best be described as (A) neutral (B) skeptical © mildly positive (D) very supportive (E) pointedly critical I still strongly feel the answer is D

Thanks Ndure, for such a quick reply. I have completely misinterpreted the sentence. The mistake that I have done is, I have searched for a word that is close to forcefulness i found it be agression. I thought this was the answer. By looking at the sentence carefully i came to know it is comparison b/w forcefulness and the missing word.

Although some consider forcefulness and ------- to be two traits desirable to the same degree, I think that making a violent effort is much less useful than maintaining a steady one. (A) promptness (B) persistence © aggression (D) skillfulness (E) lucidity please answer with explanation..

@Naresh007 even with me the problem is, i didnt get convinced why maintanance came in here. @Ndure nd Ruchir thanks..

Its answer is 'D', i seriously doubt how the answer can be 'D'.It is an ets question, so dont have any doubt about the answer.

Human relations have commanded people's attention from early times. The ways of people have been recorded ill innumerable myths, folktales, novels, Linepoems plays, and popular or philosophical essays. (5) Although the full significance of a human relationship may not be directly evident, the complexity of feelings and actions that can be understood at a glance is surprisingly great. For this reason psychology holds a unique position among the sciences. "Intuitive" knowl- (10) edge may be remarkably penetrating and can significantly help us understand human behavior, whereas in the physical sciences such commonsense knowledge is relatively primitive. If we erased all knowledge of scientific physics from our modern world, not only would (15) we not have cars and television sets, we might even find that the ordinary person was unable to cope with the fundamental mechanical problems of pulleys and levers. On the other hand, if we removed all knowledge of scientific psychology from our world, pro- (20) blems in interpersonal relations might easily be coped with and solved much as before. We would still "know" how to avoid doing something asked of us and how to get someone to agree with us; we would still "know" when someone was angry and when someone was (25) pleased. One could even offer sensible explanations for the "whys" of much of the self's behavior and feelings. In other words, the ordinary person has a great and profound understanding of the self and of other people which, though unformulated or only vaguely conceived (30) enables one to interact with others in more or less adaptive ways. Kohler in referring to the lack of great discoveries in psychology as compared with physics, accounts for this by saying that "people were acquainted with practically all territories of mental life (35) a long time before the founding of scientific psychology." Paradoxically, with all this natural, intuitive, commonsense capacity to grasp human relations, the science of human relations has been one of the last to (40) develop. Different explanations of this paradox have been suggested. One is that science would destroy the vain and pleasing illusions people have about themselves; but we might ask why people have always loved to read pessimistic, debunking writings, from (45) Ecclesiastes to Freud. It has also been proposed that just because we know so much about people intuitively, there has been less incentive for studying them scientifically; why should one develop a theory, carry out systematic observations, or make predictions about (50) the obvious? In any case, the field of human relations, with its vast literary documentation but meager scientific treatment, is in great contrast to the field of physics in which there are relatively few nonscientific books. The author implies that attempts to treat human relations scientifically have thus far been relatively (A) unilluminating (B) paradoxical © pessimistic (D) encouraging (E) uninterpretable try attempting it, please along with explanation..

please someone reply answer for this..
