Strongly supported. The older displays are deteriorating in part because of the heat of the tungsten lamps. Because the compact fluorescent lamps produce less heat than the tungsten lamps, the older displays would last longer if the tungsten lamps are replaced.

Unsupported. We know that the compact fluorescent lamps produce less heat than the tungsten lamps, but we do not know whether a display lit by many compact fluorescent lamps might be more prone to deterioration.

Unsupported. The stimulus gives us no information about how many displays are lit by each kind of lamp. We know only that “newer displays” are lit by compact fluorescent lamps and “older displays” are lit by tungsten lamps.

Unsupported. The stimulus tells us that low humidity contributes to deterioration, but it does not tell us whether the type of lamp affects humidity in any way. We know only that the lamps produce different amounts of heat.

Unsupported. We know that low humidity contributes to deterioration, but we do not know anything about the museum’s humidity levels over time.
