Question 7: Find mistakes and correct As soon as they arrived at the hotel they took the elevator room and straight to bed because they were so tired.

Explain:

Parallel structure: A and/but/or B A and B are congruent, congruent.

There should be a verb after “and” with “took” in front, and “straight” is a preposition, not a verb.

Edit: straight to bed=> went straight to bed

Translate:

As soon as they got to the hotel, they took the elevator to their room and went straight to bed because they were so tired
