IMO E

A. some of the deductive arguments are based on sense data
Still every premise need to be justified. No effect

But still we have to solve chain of premise justification.

C. some statements in the argument require no justification

­Q1. The primary purpose of the passage is to
My answer is A)
A. present an overview of a scientific controversy
The author mentions the scientific controversy in the first para and introduces its two aspects in the second and third paragraphs.

B. describe a perplexing philosophical issue
The issue does not involve pure philosophical aspect but more on the philosophy of science.

C. solve a problem in the philosophy of science
The author describes the ocntroversy but does not provide any solution to it.

D. present two opposing views on the meaning of science
The views mentioned are related to the role of sense data and logicaal arguments. There is no discussion of meaning of science.

E. detail a logical paradox inherent in the scientific method
The passage talks about a debate, not a paradox.

Q2. The author of the passage would most likely agree that justification through deductive argument could avoid the problem of infinite regress if
My answer is D)
D. the assumptions used in the argument are themselves justified
According to the passage, the justification through deductive argument could avoid the problem of infinite regress if the statements used to justify it themselves are justified or in other words, the assumptions inherent to the argument and the statements are justified.

A. some of the deductive arguments are based on sense data
The discussion on sense data comes in the third para, it is not the cause or effect of the infinite regress in deductive arguments

B. the deductive argument contains no logical inconsistencies
It talks about the statements involved to justify the deductive argument too, not just the argument. So, this answer choice does not capture the essence of the author's viewpoint.

C. some statements in the argument require no justification
The author talks about all the statements involved to must have been justified infinitely, not just some arguments not requiring justification at all.

E. the argument relies on a limited number of premises
There is no mention of the number of arguments required to justify the deductive argument.

Q3. The author of the passage would mostly agree that
My answer is E)
E. without a way of justifying scientific knowledge, science becomes dogmatic
It is evident in the following line -"Another way to avoid dogmatism in the sciences is justification through perceptual experience."

A. there is no way of justifying scientific propositions
Irrelevant to the passage

B. deductive justification and perceptual justification are the only types of scientific justification
There is no mention of the presence of only these two types anywhere in the passage.

C. some combination of deductive and perceptual justification is sufficient to justify scientific knowledge
Neither justification is sufficient as per the author and there is no mention of combination of these two types.

D. all scientific knowledge must be universal
The author does not state as such in the passage.­

1. The primary purpose of the passage is to
P1 :Debate on sense data in science.
P2: Challenges in justification methods.


A. present an overview of a scientific controversy - The scientific controversy is part of the philospical issue, B better captures the primary passage.

B. describe a perplexing philosophical issue -  Correct, in line with our summary of the passage a perplexing philosphical issue related to the sense of the data

C. solve a problem in the philosophy of science - Author is not solving the problem.

D. present two opposing views on the meaning of science - Two opposing views are presented to discuss the confusing philospical issue.

E. detail a logical paradox inherent in the scientific method - Scientifc method is used to resolve the philosphical issue.

2. The author of the passage would most likely agree that justification through deductive argument could avoid the problem of infinite regress if
Refer to the line "But this method fails because it leads to an infinite regress. The statements used to justify a proposition must themselves be justified, and so too those statements, into infinity."

A. some of the deductive arguments are based on sense data - Yes, but they still leads to infinite regress problem.

B. the deductive argument contains no logical inconsistencies - Logical consistency is not part of the argument.

C. some statements in the argument require no justification - But other which require justification may lead to infinite regress.

D. the assumptions used in the argument are themselves justified - If the assumptions are justified than the argument will not be in a circular loop explaining one after the another.

E. the argument relies on a limited number of premises-  But this still opens the possibility of infinite regress.

3. The author of the passage would mostly agree that
Refer to the line "But this method fails because it leads to an infinite regress. The statements used to justify a proposition must themselves be justified, and so too those statements, into infinity."

A. there is no way of justifying scientific propositions - The word no way indicate there is no possibility which is not correct.

B. deductive justification and perceptual justification are the only types of scientific justification - These two are presented in the passage, but we cannot infer that other than these no justification can be given.

C. some combination of deductive and perceptual justification is sufficient to justify scientific knowledge

D. all scientific knowledge must be universal -Science strives for knowledge but we cannot infer that all scientific knowledge must be universal.

E. without a way of justifying scientific knowledge, science becomes dogmatic - Correct, refer to the line "The statements used to justify a proposition must themselves be justified, and so too those statements, into infinity." This mentions that we need to justify the propositions themself first else science will become dogmatic.

IMO ­BDE­

Official Explanation

1. The primary purpose of the passage is to

Explanation


­The passage begins by introducing a debate over the role of sense data in the scientific field. The rest of the passage shows the shortcomings inherent in two views of justification in the sciences. Choice (B) is the best match for the passage.

Choice (A) is incorrect because the controversy is not in the scientific community, but in the philosophic community.

Choice (C) is incorrect because the problem is not solved.

Choice (D) is not right because the issue is not about the meaning of science.

Choice (E) is incorrect because the passage is not about the scientific method, but science in general.


The correct answer is (B).

Official Explanation

­2. The author of the passage would most likely agree that justification through deductive argument could avoid the problem of infinite regress if

Explanation


The passage describes the problem of infinite regress as one in which The statements used to justify a proposition must themselves be justified, and so too those statements, into infinity. This problem could be avoided if some of the statements in the chain do not need to be justified, as (C) states.

Choice (A) confuses the two forms of justification.

Choice (B) doesn’t matter because the point is that, even if the argument is sound, more arguments must be used to justify the argument.

Choice (D) won’t help because even if the initial argument is sound, the passage states that more arguments are needed to justify the first argument. The number of statements is not the issue, as (E) indicates.


The correct answer is (C).

Official Explanation

­3. The author of the passage would mostly agree that

Explanation


To answer this question, use Process of Elimination on the choices.

Choice (A) should be eliminated because it goes too far. The author considers two forms of justification and rejects them, but that does not mean there are not other, valid forms of justification.

Choice (B) is incorrect because the author does not indicate that those are the only two methods of justification.

The author never states that a combination of the methods is workable, so (C) is wrong.

Choice (D) is not correct because the author states that science strives for the universal. That is not the same as saying that all scientific knowledge must be universal.

Choice (E) is supported in the second paragraph, Unless we allow that scientific statements be accepted on faith alone…then we must have some way of justifying our propositions. Thus, without justification, science becomes dogmatic.


The correct answer is (E).
