Answer:
1. I think Ahmed <u>will travel</u> next month.
2. At first the man <u>didn't notice</u> that Nour <u>was watching</u> him.
Explanation:
The above answers are correct.
In the first sentence, "<em>will travel</em> " is used because it talks about what happen in the future to Ahmed.
In the second sentence, "<em>didn't notice" </em>and <em>"was watching"</em> as used in the sentence is actually the correct form of tense that fits the sentence.
