good problem deserves a bump

they are all wrong, in A what the hell is these referring to, hot sauces or endorphins? in is ambiguous

QA= Math gurus would it be ok to do the following: mult top and bottom by (x+y) (x+y)(x-y)/(x+y)(x+y)>1 then since the denominator is a square,which is always positive, you could mult accross the inquality to get: x^2 - y^2 > (x + y)^2 which after some simplification you can reduce to=> y^2 so the question is altered to ask : is y^2

if x =! - y, is ( x - y ) / ( x + y ) > 1? 1. x > 0 2. y

anyone?

semi stupid question but this really slows me down, what is a fast way to convert 72/112 to .64? it is not a clean div/simplification as far as I see it. Thanks

What do you guys think is the best game plan for the week before the test? This is assuming you have had a few solid months of good studying, done several practice tests, and work full time. I would appreciate to her your thoughts, Thanks!

Since the first part of the sentence is reffering to "the People's republic of china" (i say this because B has "its") shouldn't "the People's republic of china" come right after " Even though its per capita food supply hardly increased during two decades," and since "the peoples..." does not come after the "...decades," b, along with a,c,d are wrong. E doesn't use "its", but it still has a tense error. Am i wrong about the location of "the people's republic"?

x does not equal -y

Is there a methodical non-number picking method of doing this problem? If x /= -y, is (x - y) / (x + y) > 1 1) x > 0 2) y OA:

isn't the proved in "Although it has not been proved that..." wrong? Shouldn't it be " Although it has not been proven that..."

With all due respect to shooter, "they" is not a problem as much as "this" C(the correct ans) uses they as well.

actually upon further examination of b, "this" does not agree with sounds, that's a big no no. C also uses they

E makes no sense. E makes it seem like the proposed return to ownership applied only to lands that had been a pre-columbian form of ownership and respected by the spaniards.

What do you guys think? I thought ans should be

lesfeaves, haha I always do but, I was at work when I posted this and I had images and colors disabled on my browser so I couldn't find the spoiler button.

Automation has undermined the traditional position of labor as much by robbing workers of the special Skills that were once their most important strength than by the elimination of jobs. (A) than by the elimination of jobs (B) rather than by the elimination of a job © than by eliminating jobs (D) as by the elimination of a job (E) as by eliminating jobs OA:E

E makes no sense. E makes it seem like the proposed return to ownership applied only to lands that had been a pre-columbian form of ownership and respected by the spaniards. B- "a form of ownership..." seems like it is modifying land. C- "respected by the spaniards..." seems like it is modifying land. D- pre-columbian land was only respected in land? makes no sense. ans is A, even though it looks wrong.

Would it be correct to solve the following problem If x/= -y, is (x-y)/(x+y) > 1? 1) x > 0 2) y this way: x - y > x + y or x - y -y > y -y 1) x > 0 doesn't tell you you anything insuf 2) y 1/2 both together still don't tell you anything insuf

According to the MGMAT explanation Bose your exlp is correct, that is a pretty confusing rule.

SO WHY IS B WRONG????? Seem like the "furthermore" could be correctly used here to add additional information about why these families are especially hard hit. The only thing I see a little off about B is that if you were going to use "since" you wouldn't have the ","(comma) before it. What do you guys think?

New observations about the age of some globular clusters in our Milky Way galaxy have cast doubt on a long-held theory about how the galaxy was formed. The Milky Way contains about 125 globular clusters (compact groups of anywhere from several tens of thousands to perhaps a million stars) distributed in a roughly spherical halo around the galactic nucleus. The stars in these clusters are believed to have been born during the formation of the galaxy, and so may be considered relics of the original galactic nebula, holding vital clues to the way of the formation took place. The conventional theory of the formation of the galaxy contends that roughly 12 to 13 billion years ago the Milky Way formed over a relatively short time (about 200 million years) when a spherical cloud of gas collapsed under the pressure of its own gravity into a disc surrounded by a halo. Such a rapid formation of the galaxy would mean that all stars in the halo should be very nearly the same age. However, the astronomer Michael Bolte has found considerable variation in the ages of globular clusters. One of the clusters studied by Bolte is 2 billions years older than most other clusters in the galaxy, while another is 2 billion years younger. A colleague of Bolte contends that the cluster called Palomar 12 is 5 billion years younger than most other globular clusters. To explain the age differences among the globular clusters, astronomers are taking a second look at “renegade” theories. One such newly fashionable theory, first put forward by Richard Larson in the early 1970’s, argues that the halo of the Milky Way formed over a period of a billion or more years as hundreds of small gas clouds drifted about, collided, lost orbital energy, and finally collapsed into a centrally condensed elliptical system. Larson’s conception of a “lumpy and turbulent” protogalaxy is complemented by computer modeling done in the 1970’s by mathematician Alan Toomre, which suggests that closely interacting spiral galaxies could lose enough orbital energy to merge into a single galaxy. 137. The passage is primarily concerned with discussing (A) the importance of determining the age of globular clusters in assessing when the Milky Way galaxy was formed (B) recent changes in the procedure used by astronomers to study the formation of the Milky Way galaxy © current disputes among astronomers regarding the size and form of the Milky Way galaxy (D) the effect of new discoveries regarding globular clusters on theories about the formation of the Milky Way galaxy (E) the origin, nature, and significance of groups of stars known as globular clusters 138. According to the passage, one way in which Larson’s theory and the conventional theory of the formation of the Milky Way galaxy differs is in their assessment of the (A) amount of time it took to form the galaxy (B) size of the galaxy immediately after its formation © particular gas involved in the formation of the galaxy (D) importnce of the age of globular clusters in determining how the galaxy was formed (E) shape of the halo that formed around the galaxy 261 139. Which of the following, if true, would be most useful in supporting the conclusions drawn from recent observations about globular clusters? (A) There is firm evidence that the absolute age of the Milky Way galaxy is between 10 and 17 billion years. (B) A survey reveals that a galaxy close to the Milky Way galaxy contains globular clusters of ages close to the age of Palomar 12. © A mathematical model proves that small gas clouds move in regular patterns. (D) Space probes indicate that the stars in the Milky Way galaxy are composed of several different types of gas. (E) A study of over 1,500 individual stars in the halo of the Milky Way galaxy indicates wide discrepancies in there ages. 140. If Bolte and his colleague are both correct, it can be inferred that the globular cluster Paloma 12 is approximately (A) 5 billion years younger than any other cluster in the galaxy (B) the same age as most other clusters in the galaxy © 7 billion years younger than another cluster in the galaxy (D) 12 billion years younger than most other clusters in the galaxy (E) 2 billion years younger than most other clusters in the galaxy 141. The passage suggests that Toomre’s work complements Larson’s theory because it (A) specifies more precisely the time frame proposed by Larson (B) subtly alters Larson’s theory to make it more plausible © supplements Larson’s hypothesis with direct astronomical observations (D) provides theoretical support for the ideas suggested by Larson (E) expands Larson’s theory to make it more widely applicalbe 142. Which of the following most accurately state a finding of Bolte’s research, as described in the passage? (A) The globular clusters in the Milky Way galaxy are 2 billion years older than predicted by the conventional theory. (B) The ages of at least some globular clusters in the Milky Way galaxy differ by at leat 4 billion years. © One of the globular clusters in the Milky Way galaxy is 5 billion years younger than most others. (D) The globular clusters in the Milky Way galaxy are significantly older than the individual stars in the halo. (E) Most globular clusters in the Milky Way galaxy are between 11 and 15 billion years old. 143. The author of the passage puts the word “renegade” (line 29) in quotation marks most probably in order to (A) emphasize the lack of support for the theories in question (B) contrast the controversial quality of the theories in question with the respectable character of their formulators © generate skepticism about the theories in question (D) ridicule the scientists who once doubted the theories in question (E) indicate that the theories in question are no longer as unconventional as they once seemed

yep, like is used to compare nouns, and as is used to compare clause/verbs.
