LR Question 19 Explanation

QUESTION TEXT: When an ordinary piece of steel is put under pressure…

QUESTION TYPE: Complete the Argument

CONCLUSION: The likely conclusion is that a sheet of glass will flow if something heavy is placed on it.

REASONING: Glass is a fluid, and it flows when pressure is put on it.

ANALYSIS: This is scientific, but it isn’t very hard if you don’t let the big words scare you off.

Glass flows under pressure. So if you put pressure on glass then glass flows away from that point. The glass will be thinner at the point of pressure, and thicker at the other points.

___________

1. Nope. Likely the glass will get thinner underneath the object and thicker in other sections.
2. Glass flows away from pressure.
3. Glass doesn’t compress. It flows, because it is a liquid.
4. The stimulus says glass will flow (and not divide) as long as it doesn’t break.
5. CORRECT. Glass will flow away from the area under the object. The areas not under the object will become slightly thicker.
