Q3 :- Which of the following best describes the relationship between the first and the second paragraph of the passage?
A The first paragraph provides an illustration useful for understanding a procedure described in the second paragraph.
B The first paragraph describes a hypothetical situation whose plausibility is tested in the second paragraph.
C The first paragraph evaluates the usefulness of a procedure whose application is described further in the second paragraph.
D The second paragraph provides evidence to support a claim made in the first paragraph.
E The second paragraph analyzes the practical implications of a methodology proposed in the first paragraph.
The methodology proposed in the first paragraph involves a hypothetical technique for measuring a small solid object’s mass in space (by placing the object on a spring scale and swinging the scale in a circle at the end of a string).
The second paragraph does not discuss practical ways for using THAT hypothetical technique. In other words, the second paragraph does not analyze practical applications of the spring scale/small-solid-object method. Instead, the second paragraph describes a
different technique that is
analogous to the spring scale/small-solid-object method.
In other words, the second paragraph does not discuss (or analyze) the practical applications of the spring scale/small solid method. Instead, the second paragraph describes an analogous procedure. Furthermore, this analogous procedure is
described but is not really
analyzed.
Choice (A) is more accurate.
I hope that helps!

Suppose we were in a spaceship in free fall, where objects are weightless, and wanted to know a small solid object’s mass. We could not simply balance that object against another of known weight, as we would on Earth. The unknown mass could be determined, however, by placing the object on a spring scale and swinging the scale in a circle at the end of a string. The scale would measure the tension in the string, which would depend on both the speed of revolution and the mass of the object. The tension would be greater, the greater the mass or the greater the speed of revolution. From the measured tension and speed of whirling, we could determine the object’s mass.
Astronomers use an analogous procedure to “weigh” double-star systems. The speed with which the two stars in a double-star system circle one another depends on the gravitational force between them, which holds the system together. This attractive force, analogous to the tension in the string, is proportional to the stars’ combined mass, according to Newton’s law of gravitation. By observing the time required for the stars to circle each other (the period) and measuring the distance between them, we can deduce the restraining force, and hence the masses.

Hi
GMATNinjaThank you very much for the explanation.
In this question, the correct choice is A, but I picked the wrong choice (B).
In the passage, the word
suppose means it is going to be
hypothetical situation. For that reason, I've chosen B for the word
hypothetical situation in the answer choice B.
I've crossed out choice A because of the word
illustration. The word
illustration is definitely connected with
example, But the first para has no
example at all, unfortunately. I can't figure out that whether any
illustration in the first para?
Thanks__
