Tough RC- Moon
Question #1 *cannot* be E.
In order for a crater to have a gravity anomaly, it must have been struck the moon after any magma or material could move to the surface to replace the lost weight (i.e. after it had cooled). The whole reason that they bring the scientists in is because they need to account for a hole that doesn't have a gravity anomaly as expected. If the craters were created when the moon was elastic, then magma would have moved and displaced any lost material, thus resulting in no gravity anomaly.
This is absolutely absurd. How can we be held responsible for getting a question wrong that was clearly not thought out?

This is a detail question. So you should be able to locate the information in the passagekid_amnesiac wrote:Question #1 *cannot* be E.

"denser material from the moon's mantle rose up beneath the impactors almost immediately, compensating for the ejected material and thus leaving no gravity anomaly in the resulting basin"
That makes E correct
