For all species of higher animals, reproduction requires the production of eggs but not necessarily the production of sperm. █████ ███ ████ ███████ █████ ███████ ███ ███ ███████ ███ ████ ████████ ██ █ ████ ███████████ ███████ ██ ██████████ █████ ███████ ██████████████ ████ ███ ███ ████████ ████ ███ █████████ ████ ███████ █████ ██████ █████████ ██ ████ ██ ███ ██████ ███████ ██████ ███ ███████ ████ ████████ ████ ███████ ██████████ ████ ████ ███ ██████ ████████

Summary

For all species of higher animals, reproduction requires the production of eggs. Reproduction does not necessarily require sperm. There are some species whose members are all female. The eggs produced by a rare female-only salamander species hatch without fertilization. This has the drawback that all offspring have genetic codes nearly identical to that of the single parent, causing the species to be less adaptive than species with both male and female members.

Notable Valid Inferences

On a Must Be False question, the four wrong answers could be true. The correct answer will contradict what we know from the stimulus.

Show answer

If the statements above are █████ ████ ██ ███ █████████ █████ ██ ████ ███████

There are some ███████ ██ ███████████ ████ ████ ████ ████ ███ ██████ ████████

Could be true. We know that a rare female-only species of salamander exists, but there could also be other species of salamander with both male and female members.

There are some ███████ ██ ██████ ███████ ████ ██ █████ ███████ ███████ █████

Must be false. The first sentence tells us that reproduction for all higher animals requires the production of eggs. So it's impossible for some higher animal species to exist without producing eggs.

There is a ███████████ ██████ ██ ███████████ ███████ ██ ██████ ████████

Could be true. We know that a rare female-only species of salamander exists. It could be the case that there are many other female-only species.

Some species of ██████ ███████ ██████████ ████ ██████ ███ ████ ███████ ███ ███ ████ █████████

Could be true. We know that female-only species are less adaptive than species with both male and female members, but this does not preclude the possibility of a species with both males and females that is also not very adaptive.

Some offspring of ███████ ██ ██████ ███████ ██████████ ████ ██████ ███ ████ ███████ ████ ███████ █████ ████ ███████ ██ ███ ██████ ████ ██ ███ █████ ███████

Could be true. We know that for female-only species offspring have genetic codes identical to the single parent. But it is possible that some offspring of species with both males and females have genetic codes more similar to one parent.
