How to deal with this type of RC question?

[samwong]

The science of color management developed in response to a very specific need: the successful development of high-volume assembly lines required strict quality control across a number of parameters, including color. Engineers developed measurement devices, such as colorimeters and spectrophotometers, to create profiles of various colors. A profile from a particular machine could then be referenced to a standard color space, or set of definitions for establishing particular colors. In this way, the profile data for a specific color was "standardized" and could be transferred among different color creation and calibration machines, allowing, for example, six automobile assembly lines located in two different states to produce thousands of identically-hued silver sedans over a period of months.
In the 1990's, color management companies began adapting their color measurement expertise to the healthcare field. One company, for example, created a cholesterol test that negated the typical requirements for patients to fast before the test and have blood drawn, making the test much cheaper and easier to administer. Drops of two different liquids, digitonin and an enzyme substrate, are placed sequentially on the patient’s palm. First, the digitonin binds to cholesterol present in the skin; then, the enzyme substrate causes a color-change reaction that is dependent upon the patient’s cholesterol level. The doctor or technician can quantify the precise level by measuring the color change with a spectrophotometer. Such novel applications promise to have as far-reaching an impact on the healthcare industry as the first color measurement products had on early assembly-line businesses nearly a century ago.

Which of the following can be inferred from the passage?

A) A colorimeter can also be used in the color-based cholesterol test.

B) Color management companies will continue to develop healthcare applications.

C) Color management science would not have been developed had the automotive industry not needed the technology.

D) Color management products are applicable to industries beyond automotive and healthcare.

E) Before color management technology was developed, it was difficult to produce a large volume of cars with precisely equal colors.

In the MGMAT Online Lab Video, the instructor says that we should use the "key words/clues" in the question stem to help us locate the information in the passage that we need to answer the question.

The RC question that I listed above does not have any clues in the question stem. Instead, the clues are in each answer choices. What is the best approach to deal with this type of question?

Do you try to verify each answer choice by searching for the relevant facts in the passage? In this case, you are sacrificing time for accuracy.

Or do you answer the question without verifying the passage, using what you remember from the first reading of the passage? In this case, you are sacrificing accuracy for time.

I have a tough time dealing with this type of question. The fact that it's an Inference question makes it even more challenging.

Thank you.

You're right; there aren't any keywords in the question. In effect, this question forces you to hunt randomly through the entire passage for a single detail.

That isn't how the official questions work. If an official RC question concerns details, it will always contain a keyword(s) to point you to those details.

I'll submit this to the CAT team; it should be modified to better reflect GMAC's methodology. Thanks.

what's wrong with option C? I chose C because of the first sentence: ' The science of color management developed in response to a very specific need: '

Actually, I think both C and E are correct.

[RonPurewal]

choice C implies that no one else (outside the automotive industry) ever would have developed this technology, for any reason, ever.

not only is that unsupported by the text here, but it's also absurd! if the automotive people hadn't developed the technology, someone else eventually would have.
