Can you please diagram and explain this

This passage does not contain any Sufficient & Necessary statements. So there is nothing to diagram. Since we are faced with an argument, we must first break it down.

Conclusion: a person being prevented from sleeping solely by such thoughts would be able to fall asleep by closing the eyes and counting sheep

Why? We are told that the kind of thoughts that keep a person from falling asleep can arise in either half of the brain. Further we are told that the activity of closing ones eyes and counting sheep fully occupies the left half of the brain with counting and the right half of the brain with imagining sheep, thereby excluding the sleep-preventing thoughts.

Answer choice (C) states: "Thoughts of sheep would not keep the person awake at that time."

We are told that imagining sheep will occupy the right half of the brain, while counting them will occupy the left half of the brain because that will prevent the kind of thoughts that keep a person from falling asleep. However, if - for some reason - the thought of sheep was the exact thought keeping a person awake, then the act of picturing sheep will not exclude sleep-preventing thoughts, i.e. thinking of sheep will only continue to keep the person awake.

Thus, answer choice (C) is the correct answer.

Hope that clears things up! Please let us know if you have any other questions.

Why could it not be D?

Hello! I've gone ahead and read all of the explanations but I'm still a bit lost. (D) initially seemed like the most reasonable answer even though "whenever" is much broader than what the passage discusses. Thank you

@sojiman @Rebeccas-Alvarado the problem with (D) is that it is not necessarily true. We are not talking about "thoughts of sheep", we are talking about counting sheep.

Additionally, nothing in the stimulus supports this notion that any time a person thinks about sheep, sleep will be induced.

Hope that helps! Please let us know if you have any other questions.

Hello!! I would like to understand why it cannot be "B"

Hi @Maria-Marin,

Thanks for the question! Let’s take a look at what the passage is telling us. We’re told that sleep-preventing thoughts can be excluded by counting sheep because doing so occupies both sides of the brain, and thus, counting sheep can help people who can’t sleep solely because of those thoughts. The passage then asks us which of the following statements must be true. Notice that nowhere in the passage does it state that a person has to normally have a difficult time falling asleep. Perhaps a person can normally fall asleep, but one night, they have sleep-preventing thoughts for whatever reason. There’s nothing in the passage that suggests that that person wouldn’t be able to fall asleep by employing the sheep counting strategy, since it’s likely that they would still be able to occupy both halves of their brain by counting sheep, which would exclude the thoughts and help them sleep. We definitely can’t conclude that only people who normally have a difficult time falling asleep can employ the sheep counting strategy, and so (B) cannot be the right answer.

Hope this helps! Feel free to ask any other questions that you might have.
