A1: Let's analyze the sentences one by one to determine if they are grammatically correct.

1. The accident left it possible for him to take a rest in the hospital. - This sentence is grammatically correct.

2. The heavy snow left it impossible for him to go to work by car. - This sentence is also grammatically correct.

3. Keep it a secrte to go to the PC room with me. - There's a typo in this sentence. It should be "secret" instead of "secrte." So, the correct sentence would be "Keep it a secret to go to the PC room with me."

4. Keep it a secret that you go to the PC room with me. - This sentence is grammatically correct.

5. I took it for granted that the shop was open. - This sentence is grammatically correct.

A2: "Taking something for granted" means assuming or expecting something to be true without questioning or verifying it. It implies not fully appreciating or recognizing the value or importance of something because it is perceived as common or normal. It does carry the connotation of considering something as natural or expected.
