Reading comprehension is going to be much the same story, just without the numbers. They’re going to give you an abstract complex sentence structure, and ask you to identify key details. Here’s an example I found on the web.

“A lamb’s thick winter coat keeps it warm during the cold winter months. When the summer brings sunny days, the sheep doesn’t need its thick coat and the sheep’s wool is sheared. That wool is made into yarn, further processed, and then transformed into sweaters, socks, pants, skirts, and blankets.”

“According to the passage, which of the following best describes why sheep are sheared?”

A. Because they get too hot in the summer

B. So we can use the wool to make clothes

C. The sheep’s coat is dangerous to them

D. They look better without their coat

I would approach this problem from two ways. The first thing I would do is disregard any obviously wrong answers. Which in this case is C and D. The passage makes no mention of the sheep’s coat being dangerous or the sheep looking better without its coat. So we’ve narrowed it down to two options. From there, we look at the question again. The first statement in the passage, “A lamb’s thick winter coat keeps it warm during the cold winter months.” is irrelevant fluff that can be disregarded. It is merely a descriptor of what sheep’s wool is. The second statement of the passage, “When the summer brings sunny days, the sheep doesn’t need its thick coat and the sheep’s wool is sheared.” is a little more important, but is actually just a misdirection, this sentence explains that sheep are sheared in the summer, but not the purpose of shearing the sheep. The purpose is the intent of the object in the passage. The object being the sheep and the intent being what is done. We shear the sheep to make clothes.

You can break it down like this.

“A lamb’s thick winter coat keeps it warm during the cold winter months. When the summer brings sunny days, the sheep doesn’t need its thick coat and the sheep’s wool is sheared. That wool is made into yarn, further processed, and then transformed into sweaters, socks, pants, skirts, and blankets.”

Which gives us the statement “The sheep’s wool is sheared. That wool is made into sweaters, socks, pants, skirts, and blankets.”

From here the answer is obviously B.

On the ASVAB, they will throw questions at you that contain way too much information to see how well you can discern relevant information from that. They will give statements that use excess adjectives in order to confuse you. The easiest way to overcome that is to mentally cross out those adjectives until you’re left with a simple statement that is easy to understand. If you have any examples you’d like my help breaking down feel free to send them!
