Why another answer cannot be the answer?

The below is a text question. Can you get the answer first?

We are inclined to remember some information better when it is related to a location, which is called episodic memory. We all remember some information because it is related to a location. The car that you drive when you are first learning how to drive will be easier for you to drive than other cars. Even though most cars have similar designs, you will remember your instruction and associate it

with this particular car. Taking your driving test in another car will make the experience more difficult. So it can be said that episodic memory has an important component called “invisible information.” Students have more trouble solving math problems in English classroom than they do in their math classroom. Why? The walls, desks, overheads, chalkboards, and even the math teacher are covered with invisible information. In other words, the content of the room.

.

? becomes part of the context of the memory

? constitutes invisible information of instruction

? influences your selection of the visual experience

? is replaced by preferred components in the memory

? enables the invisible information to disappear temporarily

The answer is #1, and I get it right?

But I cannot say #2 is impossible. #2 has a bit possible though #1 seems much better.

I'm not sure this question is proper to ask. But I have racked my brain for a few days and still don't have any good idea about it.

Thanks In Advance.
