In one study engineering students who prepared for an exam by using tooth-picks and string did no worse than did similar students who prepared by using an expensive computer with sophisticated graphics. In another study, military personnel who trained on a costly high-tech simulator performed no better on a practical exam than did similar personnel who trained using an inexpensive cardboard model. Therefore, one should not always purchase technologically advanced education tools.

Which of the following principles, if valid, most helps to justify the reasoning above?

(A) One should use different educational tools to teach engineering to civilians than are used to train military personnel.
(B) High-tech solutions to modern problems are ineffective unless implemented by knowledgeable personnel.
(C) Spending large sums of money on educational tools is at least as justified for nonmilitary training as it is for military training.
(D) One should not invest in expensive teaching aids unless there are no other tools that are less expensive and at least as effective.
(E) One should always provide students with a variety of educational materials so that each student can find the materials that best suit that student’s learning style.

Therefore, one should not always purchase technologically advanced education tools.

Which of the following principles, if valid, most helps to justify the reasoning above?

(A) One should use different educational tools to teach engineering to civilians than are used to train military personnel.-- Big no. No relative comparison.
(B) High-tech solutions to modern problems are ineffective unless implemented by knowledgeable personnel. --no.
(C) Spending large sums of money on educational tools is at least as justified for nonmilitary training as it is for military training.--goes against
(D) One should not invest in expensive teaching aids unless there are no other tools that are less expensive and at least as effective.--Correct
(E) One should always provide students with a variety of educational materials so that each student can find the materials that best suit that student’s learning style.--- No

Analysis : Argument cites two separate study and then draws a generic conclusion. The reasoning connecting the two arguments is same. Option D is the right answer

(C) Spending large sums of money on educational tools is at least as justified for nonmilitary training as it is for military training.
(D) One should not invest in expensive teaching aids unless there are no other tools that are less expensive and at least as effective.
(E) One should always provide students with a variety of educational materials so that each student can find the materials that best suit that student’s learning style.

Question says:-
Performance of engineering students using tooth-picks and string = or > students who prepared by using an expensive computer

Performance of military students using inexpensive materials = or > military personnel who trained on a costly high-tech simulator performed

Conclusion is that one should not always purchase the expensive tools.

We can justify the reasoning if we could tell that expensive or high performing tools is not a promise of better performance. So, if there are other non expensive products available, one can look for those products.

(A) One should use different educational tools to teach engineering to civilians than are used to train military personnel. Conclusion is not talking about different techniques used for civilians and military people.
(B) High-tech solutions to modern problems are ineffective unless implemented by knowledgeable personnel. 'knowledgeable personnel' is not spoken about
(C) Spending large sums of money on educational tools is at least as justified for nonmilitary training as it is for military training. Spending large sum of money is actually not justified according to the argument.
(D) One should not invest in expensive teaching aids unless there are no other tools that are less expensive and at least as effective. In line with our thinking above
(E) One should always provide students with a variety of educational materials so that each student can find the materials that best suit that student’s learning style. we are concerned about expensive or sophisticated and non-expensive or simple materials and not about variety of materials.

(A) One should use different educational tools to teach engineering to civilians than are used to train military personnel.Out of scope
(B) High-tech solutions to modern problems are ineffective unless implemented by knowledgeable personnel. Potential Trap- Incorrect because passage doesn't talk about implementation
(C) Spending large sums of money on educational tools is at least as justified for nonmilitary training as it is for military training. Out of scope
(D) One should not invest in expensive teaching aids unless there are no other tools that are less expensive and at least as effective. Speaks about effectiveness of the teaching aid, hence justifies the reasoning
(E) One should always provide students with a variety of educational materials so that each student can find the materials that best suit that student’s learning style Out of scope, does not talk about learning styles

(A) One should use different educational tools to teach engineering to civilians than are used to train military personnel.
(B) High-tech solutions to modern problems are ineffective unless implemented by knowledgeable personnel.
(C) Spending large sums of money on educational tools is at least as justified for nonmilitary training as it is for military training.
(D) One should not invest in expensive teaching aids unless there are no other tools that are less expensive and at least as effective.
(E) One should always provide students with a variety of educational materials so that each student can find the materials that best suit that student’s learning style.

The Argument concludes that purchasing technologically advanced educational tools does not lead to improved results by illustrating with examples where the use of technologically advanced tools by engineering students and military personnel did not automatically lead to better results.

(A) One should use different educational tools to teach engineering to civilians than are used to train military personnel - The argument does not compare educational tools used by civilian and military personnel. Irrelevant.

(B) High-tech solutions to modern problems are ineffective unless implemented by knowledgeable personnel - This could arguably be an assumption of the argument, but it does not justify the reasoning in the argument.

(C) Spending large sums of money on educational tools is at least as justified for nonmilitary training as it is for military training - The argument does not compare money spent on educational tools and military training. Irrelevant.

(D) One should not invest in expensive teaching aids unless there are no other tools that are less expensive and at least as effective - This statement is in line with the conclusion, and summarizes the reason for the conclusion succinctly.

(E) One should always provide students with a variety of educational materials so that each student can find the materials that best suit that student’s learning style - The argument does not talk about the preferences of students for different types of educational materials. Irrelevant.

B and D are closed, but B just repeats the argument itself.
The question is a strengthen question, and the pattern in this question is to understand the main idea.
