Conservationist: The population of a certain wildflower is so small that the species is headed for extinction. ████████ ████ ██████████ ███ ███████████████ ████ █ ███████ ███████ ████████████ ██████ █████████ ██████ ██████ ████ █████████████████ █████ ██████ ██ █ ███████████ ██████████ ██ ████████████████ ████████ ███ █████ ██████ █████████ ██ ██████████ ████ ███ ████████████ ██████ █████ ████████ ███ ██████ █████ ██████ ████████ ████ ███ ███████████ █████████████ ██ ███ ████ █████ ██ ██████████ █████ ████ ██ ███ ██████████ ██ ███ ██████

Summary

In an attempt to save certain wildflowers from extinction, the conservationist suggests cross-pollinating them with daisies to produce hybrids, which is the only way to prevent the elimination of the wildflower in its range.

Notable Assumptions

The conservationist assumes that preventing the extinction of this wildflower is a worthwhile goal, since it’s never actually established that the wildflower’s extinction should be prevented.

Also, the conservationist assumes that these hybrids will be able to survive over time. While it’s established that they’re viable, meaning that the seeds will grow into plants, the argument does depend on the assumption that the hybrid population will last over time. If the hybrid population were to die off for some other reason, then the conservationist’s plan to save the wildflowers would fail.

Show answer

Which one of the following ██ ██ ██████████ ██ █████ ███ █████████████████ █████████ ████████

The wildflower currently ██████████ ████ ██ ███████ ██████

The argument establishes that hybridization is the only way to prevent the wildflower’s extinction, so even if they currently reproduce in other ways, those other ways still wouldn’t allow the flowers to survive.

The domesticated daisy ███ ████ ████ ████ ██████ ████ ████ ████ ██ ███ ████████████ ██████

The argument establishes that the wildflower can cross-pollinate with the daisies, so it doesn’t matter where the daisies were bred from.

Increasing the population ██ ███ ██████████ ████ ████ ██████ ███ ██████

The conservationist is only concerned with preventing the wildflower’s extinction in its range, so its range doesn’t need to expand.

Wildflower-daisy hybrids will ██ ████ ██ ██████████

This must be true in order for the conservationist’s plan to work. If the hybrids couldn’t reproduce, then cross-pollinating the wildflowers with daisies would fail to prevent the former’s extinction since the population of hybrids would also go extinct.

The domesticated daisy ████ ███████████████ ████ ███ █████████ ██████

For the conservationist’s plan to work, the daisies only need to cross-pollinate with the wildflowers. It doesn’t matter whether or not they can cross-pollinate with other plants.
