It can be inferred that the greenhouse roof

The option C doesn't make sense. The mixture of the air is facilitated because of the Roof but it says "This heated air, drawn down from the roof" That means the air is drawn down and the roof will play no role now. Why option C as correct option?

Hey Pradhyumn,
I see what you're saying here. However, the question doesn't ask us if the roof is 100% responsible for the listed choices. Rather, we just need choices that the roof was designed to "allow." Certainly, the collection of moisture was part of the plan in designing the roof this way. Hence, the roof was designed in order for this mixture of air to occur. Sur,e the roof doesn't do all of the work, but it helps the process. And that's all we need.

Hey Chris, for the option B there is no mention in the passage of the entry of sunlight into the greenhouse to make the plants grow. To make plants grow??? should we assume that?? is that not an outside information again???

Hi Prashant,
I would say that we can consider common knowledge the fact that plants need light to grow. So, we can say that the entry of sunlight will help/make plants in the greenhouse grow :)
Does that make sense?

Hi, Cydney! I have the same question with Prashant. You said that we could use common knowledge to choose answer choice B. However, I think that the strategy when doing GRE like reading comprehension question is the "idiot principle", which means we can only use the information based on what the passage mentions. I remember Chris mentions this in his introduction video lessons. And I've also read the passage at least 3 times and didn't find any information about answer choice B). So why could we choose B as one of the correct answer? How can we solve this paradox?

Hi Hugo,
You're right that we shouldn't use outside information on the GRE! However, as Cydney mentioned, it's OK to use basic, common knowledge. That is, we can use information that every test taker can reasonably be expected to know. The fact that sunlight makes plants grow is common knowledge, so we can use that for this question!
I hope that helps :)

Hi, Sam,
Don't you think that to use common knowledge holds a dangerous precedent, given that what is common knowledge for one may not be for another person? Soon, how exactly define common knowledge can be a hard task once the test taker should be able to decide one fact as common or not during the test.

Hi Diogo,
The GRE definitely expects you to bring certain aspects of knowledge to bear on the exam. Knowing that sunlight is involved in the growth of plants is certainly something that the GRE may expect you to know and use on the test, as this question written by the same people who write the actual GRE illustrates.
