The hypothesis of an expanding Earth has never attracted notable support, and if it were not for the historical example of continental drift, such indifference might be a legitimate response to an apparently improbable concept. It should be remembered, however, that drift too was once regarded as illusory, but the idea was kept alive until evidence from physicists compelled geologists to reinterpret their data.
Of course, it would be as dangerous to overreact to history by concluding that the majority must now be wrong about expansion as it would be to reenact the response that greeted the suggestion that the continents had drifted. The cases are not precisely analogous. There were serious problems with the pre-drift world view that a drift theory could help to resolve, whereas Earth expansion appears to offer no comparable advantages. If, however, physicists could show that the Earth’s gravitational force has decreased with time, expansion would have to be reconsidered and accommodated.

If, however, physicists could show that the Earth’s gravitational force has decreased with time, expansion would have to be reconsidered and accommodated.
Q1. The passage indicates that one reason why the expansion hypothesis has attracted little support is that it will not
(A) overcome deficiencies in current geologic hypotheses
(B) clarify theories concerning the Earth’s gravitational forces
(C) complement the theory of continental drift
(D) accommodate relevant theories from the field of physics
(E) withstand criticism from scientists outside the field of geology
Q2. The final acceptance of a drift theory could best be used to support the argument that
(A) physicists are reluctant to communicate with other scientists
(B) improbable hypotheses usually turn out to be valid
(C) there should be cooperation between different fields of science
(D) there is a need for governmental control of scientific research
(E) scientific theories are often proved by accident
Q3. In developing his argument, the author warns against
(A) relying on incomplete measurements
(B) introducing irrelevant information
(C) rejecting corroborative evidence
(D) accepting uninformed opinions
(E) making unwarranted comparisons
Q4. It can be deduced from the passage that the gravitational force at a point on the Earth’s surface is
(A) representative of the geologic age of the Earth
(B) analogous to the movement of land masses
(C) similar to optical phenomena such as mirages
(D) proportional to the size of the Earth
(E) dependent on the speed of the Earth’s rotation

Answer 1:
(A) overcome deficiencies in current geologic hypotheses
The other geological theory of continental thrift, which was earlier considered as an illusion. the hypothesis that follows here is earlier rejection and then acceptance. so the expansion theory gained some popularity because it's also considered as an assumption, which might prove its validity later, if explored like the continental drift theory.) CORRECT
(B) clarify theories concerning the Earth’s gravitational forces
The mention of gravitational force is suggested to consider the expansion theory validity, not the other way round INCORRECT
(C) complement the theory of continental drift
nope, continental drift and expansion theory are contrasting in nature INCORRECT
(D) accommodate relevant theories from the field of physics
No other theory is taken into consideration in the passage INVALID
(E) withstand criticism from scientists outside the field of geology
NO such criticism is mentioned/displayed in the passage INCORRECT
Answer is A
Answer 2:
(A) physicists are reluctant to communicate with other scientists
(Nothing, such as mentioned in the passage) Can't Predict.
(B) improbable hypotheses usually turn out to be valid
(well, this statement generalizes all hypotheses which are usually valid? Not really.) INCORRECT
(C) there should be cooperation between different fields of science
(Yes If all fields of science work altogether, the hypothesis would get its validity sooner than later, like in the case of drifting theory where the occurrence of one theory is suggested by all science field experts) CORRECT
(D) there is a need for governmental control of scientific research
No government interference is suggested in the passage INCORRECT
(E) scientific theories are often proved by accident
(All scientific theories are proven with the help of uncertain event? NO) Incorrect
Answer is C
Answer 3:
(A) relying on incomplete measurements
(well, the expansion hypothesis with the help of gravitational force has not been elaborated in the passage. It is meant to be explored further, not really tested) INCORRECT
(B) introducing irrelevant information
No irrelevant information is suggested in the passage INCORRECT
(C) rejecting corroborative evidence
The author doesn't reject any proven facts or evidence INCORRECT
(D) accepting uninformed opinions
No such opinion is suggested or explained in the passage INCORRECT
(E) making unwarranted comparisons
In the second paragraph, the last 5th line suggests that the expansion theory has no comparative advantage, which proves this statement validity CORRECT
Answer is E
Answer 4:
(A) a representative of the geologic age of the Earth
Age is not a determining factor in the passage INCORRECT
(B) analogous to the movement of landmasses
No such comparison is explained with respect to continental drift INCORRECT
(C) similar to optical phenomena such as mirages
Mirages are not a suggested part of the passage INCORRECT
(D) proportional to the size of the Earth
Yes, the gravitational force is considered as a scaling method to deduce whether expansion theory exists and expansion(increase in size) of the Earth) CORRECT
(E) dependent on the speed of the Earth’s rotation
Earth's speed is not considered INVALID

Q2. The final acceptance of a drift theory could best be used to support the argument that
(B) improbable hypotheses usually turn out to be valid
The word 'usually' is not correct. It is too strong to use usually it turns out to be valid. Otherwise this option is good.
(C) there should be cooperation between different fields of science
Nothing much to say, the relevant portion of passage is given below -
"It should be remembered, however, that drift too was once regarded as illusory, but the idea was kept alive until evidence from physicists compelled geologists to reinterpret their data."
