Q5 - Natural History Museum contains several displays

[ohthatpatrick]

Question Type:
Inference (most strongly supported)

Stimulus Breakdown:
Causal: Some of the animal skins at a museum are deteriorating because the their tungsten lights create a dry/hot atmosphere.
Contrast: Fluorescent lamps designed for museums give off less heat, but just as much light.

Answer Anticipation:
What safe, moderate idea would we reach by combining some of the info we've received? It sounds like we should try to switch animal skins over to fluorescent lights since they reduce the dry/hot problem that tungsten lights create and that cause the animal skin to deteriorate.

Correct Answer:
A

Answer Choice Analysis:
(A) This seems pretty fair. It's too sure to be provable ("Some WILL last longer"), but it's very supportable.

(B) Unknown Comparison: We can't judge "few tungsten" vs. "many fluorescent".

(C) Unknown Comparison: We can't judge whether the museum is more tungsten or fluorescent (we have reason to believe it SHOULD be more fluorescent, but not that it IS)

(D) The fluorescent lights are same in terms of light, less in terms of heat, and ??? in terms of humidity. It wasn't mentioned.

(E) Unknown Comparison: There's no way to compare humidity from a while ago to humidity today.

Takeaway/Pattern: The correct answer to "most strongly support" is often gist-y. We can't totally prove it, but it's supportable and goes with the momentum of the information. Inference loves to test Conditional, Causal, Quantitative, and Comparison/Contrast language. Here, the Contrast between tungsten and fluorescent had a Causal impact on the deterioration of animal skins.

Can somebody tell me why C is the correct answer?

1) You may be looking at section 3 games, where the answer is C for number 5.
2) The answer is not C it is A.
3) If they were to replace the tungsten lamps that currently illuminate the older displays with compact fluorescent lamps, the lamps would effectively reduce the amount of heat, hence allowing the older to displays to last a longer period of time.

Yes! Good explanation and welcome to the forum! Indeed, you are correct. The answer is (A) and you are right about why:

If they were to replace the tungsten lamps that currently illuminate the older displays with compact fluorescent lamps, the lamps would effectively reduce the amount of heat, hence allowing the older to displays to last a longer period of time.

(B) is the opposite of what we've been told.
(C) is out of scope. More? We don't know how many there are of anything.
(D) is too extreme"”we don't actually know that this will not happen. Maybe there could just be low humidity some day for some other reason.
(E) is wayyyy out there.
