1-M: It is almost impossible to find a person between the ages of 85 an 90 who primarily uses the left hand.
Q: Seventy to ninety years ago, however, children were punished for using their left hands to eat or to write and were forced to use their right hands.
Q’s response serves to counter any use by M of the evidence about 85 to 90 year olds in supports of which one of the following hypotheses?
(A) Being born right-handed confers a survival advantage.
(B) Societal attitudes toward handedness differ at different times.
(C) Forcing a person to switch from a preferred hand is harmless.
(D) Handedness is a product of both genetic predisposition and social pressures.
(E) Physical habits learned in school often persist in old age.

2-Mary, a veterinary student, has been assigned an experiment in mammalian physiology that would require her to take a healthy, anesthetized dog and subject it to a drastic blood loss in order to observe the physiological consequences of shock. The dog would neither regain consciousness nor survive the experiment. Mary decides not to do this assignment.
Mary’s decision most closely accords with which one of the following principles?
(A) All other things being equal, gratuitously causing any animal to suffer pain is unjustified.
(B) Taking the life of an animal is not justifiable unless doing so would immediately assist in saving several animal lives or in protecting the health of a person.
(C) The only sufficient justification for experimenting on animals is that future animal suffering is thereby prevented.
(D) Practicing veterinarians have a professional obligation to strive to prevent the unnecessary death of an animal except in cases of severely ill or injured animals whose prospects for recovery are dim.
(E) No one is ever justified in acting with the sole intention of causing the death of a living thing, be it animal or human.

por favor, El Señor explain your answer choices.

IMO D

(A)Being born right-handed confers a survival advantage.(Doesnt mention that being lefthanded offers any advantage)
(B) Societal attitudes toward handedness differ at different times.(Does not mention how the attitudes differ)
(C) Forcing a person to switch from a preferred hand is harmless.(Does not mention whether changing to left handed is harmless
(D) Handedness is a product of both genetic predisposition and social pressures.
(E) Physical habits learned in school often persist in old age.(We are not sure whether these habits were learned in school)

IMO A

(A) All other things being equal, gratuitously causing any animal to suffer pain is unjustified.
(B) Taking the life of an animal is not justifiable unless doing so would immediately assist in saving several animal lives or in protecting the health of a person.(The argument does not mention whether taking a life is justifiable if it assists in saving the life of others)
(C) The only sufficient justification for experimenting on animals is that future animal suffering is thereby prevented.(Again, does not mention whether taking a life is justifiable if future animal suffering is prevented)
(D) Practicing veterinarians have a professional obligation to strive to prevent the unnecessary death of an animal except in cases of severely ill or injured animals whose prospects for recovery are dim.(Again, out of scope)
(E) No one is ever justified in acting with the sole intention of causing the death of a living thing, be it animal or human.(Too extreme)

1-M: It is almost impossible to find a person between the ages of 85 an 90 who primarily uses the left hand. Clearly, being born right-handed confers a survival advantage.
Q: Seventy to ninety years ago, however, children were punished for using their left hands to eat or to write and were forced to use their right hands. Thus, it could be that many people aged 85 to 90 were born left handed, but were forced to change hands

A

2-Mary, a veterinary student, has been assigned an experiment in mammalian physiology that would require her to take a healthy, anesthetized dog and subject it to a drastic blood loss in order to observe the physiological consequences of shock. The dog would neither regain consciousness nor survive the experiment. Mary decides not to do this assignment.
Mary’s decision most closely accords with which one of the following principles?
(A) All other things being equal, gratuitously causing any animal to suffer pain is unjustified. (there is a purpose, there is no pain)
(B) Taking the life of an animal is not justifiable unless doing so would immediately assist in saving several animal lives or in protecting the health of a person. (OK)
(C) The only sufficient justification for experimenting on animals is that future animal suffering is thereby prevented. (This may be accomplished by the research)
(D) Practicing veterinarians have a professional obligation to strive to prevent the unnecessary death of an animal except in cases of severely ill or injured animals whose prospects for recovery are dim. (She is just a student)
(E) No one is ever justified in acting with the sole intention of causing the death of a living thing, be it animal or human. (this is not the sole intention)

OA - A and B

[Dream_GMAT]

Can some one explain why the answer for 1 is A?

[abhishek_mumbai]

I still think answer of 1st Q is E..
The questions is not to refute the hypothesis but to refuse the use of evidence by M in support of hypothesis..
When (A) states about survival advantage, how M with 85-90 years strengthen it even..


Look at E.. E mentions that things taught in schools persist in old age and M strengthen that there aren't anyone left handed and old.. - by infer that child learnt to use right hand.. Q refutes it and mention that it was done by scolding..
while I am writing this note, I realized few gaps in my own reasoning too..
E doesn't sound great to me but still better than A.
