I still have a last question:

In the reading comprehension the sentence is " When we went to complain to the travel agency, as a compensation for all the incovenience we had been caused, they offered us a weekend for two in Rome organized by the same tour operator." (Shall I leave it as it is or change it?)
The question could be: What did the travel agency offer them as a compensation? (or just "as compensation"?)

Thank you so much.

Leave it as is.

"as copensation"

Leave it as is.

"as compensation"

To answer the question, "What did the travel agency offer them as compensation?" you can extract the relevant information from the sentence:

"When we went to complain to the travel agency, as a compensation for all the inconvenience we had been caused, they offered us a weekend for two in Rome organized by the same tour operator."

Based on this sentence, the travel agency offered them "a weekend for two in Rome organized by the same tour operator" as compensation.

So to answer your question, you can leave the sentence as it is, as it clearly states what the travel agency offered them as compensation.
