The type of sound made is irrelevant as an assumption as it has already been established that the sounds are detectable.

Marine biologist: While we have known that larger marine animals such as whales and dolphins communicate using sound, the fact that smaller marine animals also use sound is a relatively new discovery. These low-frequency sounds produced by animals in the mesopelagic zone--that area between 200 and 1,000 meters below the ocean surface--may be evidence that these smaller animals can communicate when it is time to feed. Understanding more about which marine populations use sound would lead to a better understanding of the ocean's ecosystem, including which animals feed on animals from the mesopelagic zone.

Indicate two different statements as follows: one statement identifies an assumption required by the marine biologist's argument and the other identifies a possible fact that, if true, would provide significant logical support for the required assumption. Make only two selections, one in each column.

Incorrect.

This statement would have no bearing on the author's conclusion regarding the feeding of marine animals whether inside or outside of the mesopelagic zone.

Well done! [[snippet]] In order for the marine biologist to conclude that understanding the use of sound in marine animal communication could aid in knowing which animals outside the mesopelagic zone feed on those from the zone, then the *required assumption* is that these animals are *only* eaten by animals outside of the zone and not within it. The *possible fact* that best supports this **assumption** is that the marine animals inside the mesopelagic zone must leave it in order to feed, thus exposing themselves to the other marine animals.

Correct!

Incorrect.

Remember, the possible fact must provide significant logical support for the assumption required. This answer choice would have little effect on the assumption.

Incorrect.

Remember, the possible fact must provide significant logical support for the assumption required and that you must choose two different statements.

The sound is about five decibels louder than the ocean's background noise.

Sound travels farther underwater than was first suspected.

The sound made by the smaller animals is a buzzing or humming that goes on for up to two hours.

Marine animals found in the mesopelagic zone must feed outside the zone.

Marine animals that once used chemical cues to indicate feeding times have been found to also use sound.

Marine animals producing sounds in the mesopelagic zone are only eaten by animals living outside of the zone.
