Logic Breakdown

Passage Summary: A museum has animal skin displays. The older ones are getting damaged by the heat from old-style light bulbs. The museum is now using newer bulbs that stay cooler but are just as bright.

Reasoning: Older museum displays are deteriorating due to heat from tungsten lamps, while newer displays use compact fluorescent lamps that provide equal light but generate less heat.

Analysis: This is a 'Most Strongly Supported' question, so we are looking for a deduction based on the provided facts. We know that heat is a primary culprit in the deterioration of the animal skins and that the newer lamps mitigate this specific threat. Therefore, it is highly likely that the newer lamps will cause less damage to the displays than the older tungsten ones did. Look for an answer choice that connects the reduction in heat to a reduction in the risk of skin deterioration.

5.

The statements above, if true, most strongly support which one of the following?

Correct Answer
A
Replacing hot tungsten lamps with lower-heat CFLs would reduce one known cause of deterioration (heat), so it’s well supported that at least some older displays would last longer.
