Example 7

I understand why E is correct, and I understand why the majority of answers are wrong, but I am just struggling to fully grasp why C is incorrect?

Hi @Conner-Judson,

C is quite close to being correct but there is one issue.

The passage reads: "for anything that far away [as a quasar] to appear from the Earth the way quasars do, it would have to burn steadily at a rate that produces more light than 90 billion suns would produce."

In comparison, the answer choice reads: "anything that from Earth appears as bright as a quasar does must produce more light than would be produced by 90 billion suns."

These are nearly identical statements; however, the answer choice fails to include "that far away." In failing to include this, the answer choice is saying that anything that appears as bright as a quasar from Earth must produce more light than is produced by 90 billion suns. It is entirely possible that our moon appears as bright as a quasar from Earth but we know that it does not produce more light than 90 billion suns. Therefore, this answer choice is incorrect.

Hope this is helpful! Please let us know if you have any further questions.
