LSAT Question Complete Explanation

Let's first break down the given passage into its premises and conclusion:

Premise 1: More computer programs are being produced that provide solutions to mathematical problems in engineering.

Premise 2: It is increasingly unnecessary for practicing engineers to have a thorough understanding of fundamental mathematical principles.

Conclusion: Less emphasis should be placed on mathematical principles in training engineers, so that space in the engineering curriculum will be available for other important subjects.

To better understand this argument, let's use a simple example. Imagine there are more and more calculators being produced that can solve complex math problems. As a result, people don't need to know how to solve these problems on their own. Therefore, in schools, less emphasis should be placed on teaching complex math, and more time should be spent on other subjects.

Now, let's come up with an "Evaluate" question for this argument: "Is a thorough understanding of mathematical principles necessary for effectively using these computer programs?"

The question type of this problem is "Weaken," so we need to find the answer choice that most seriously weakens the argument given for the recommendation above.

a) The effective use of computer programs that provide solutions to mathematical problems in engineering requires an understanding of mathematical principles.

This answer choice directly addresses our "Evaluate" question, stating that an understanding of mathematical principles is necessary for effectively using these computer programs. If this is true, then the conclusion that less emphasis should be placed on mathematical principles in training engineers is undermined. Therefore, this is the correct answer.

b) Many of the computer programs that provide solutions to mathematical problems in engineering are already in routine use.

This answer choice doesn't weaken the argument, as it just confirms that these programs are already being used. It doesn't address whether engineers still need to understand mathematical principles or not.

c) Development of composites and other such new materials has meant that the curriculum for engineers who will work in industry must allow time for teaching the properties of these materials.

This answer choice might seem tempting, as it introduces other subjects that need to be taught. However, it doesn't address whether understanding mathematical principles is still necessary for engineers or not. Therefore, it doesn't weaken the argument.

d) Most of the computer programs that provide solutions to mathematical problems in engineering can be run on the types of computers available to most engineering firms.

This answer choice is irrelevant to the argument, as it only talks about the compatibility of the computer programs with the available computers. It doesn't address the need for understanding mathematical principles.

e) The engineering curriculum already requires that engineering students be familiar with and able to use a variety of computer programs.

This answer choice strengthens the argument by stating that engineering students are already familiar with computer programs. It doesn't weaken the argument, as it doesn't address whether understanding mathematical principles is still necessary.

In conclusion, the correct answer is (a), as it most seriously weakens the argument by stating that an understanding of mathematical principles is necessary for effectively using the computer programs that provide solutions to mathematical problems in engineering.
