Answer:
1. L'Histoire
2. Un diplome
3. L'arithmetic
4. Difficile
5. Une bourse d'etude
6. La geologie
7. Une note
8. La literature
Explanation:
Most of these are simply guesses, I suggest to double check whenever you can.
Remember for the articles feminine la / une and masculin le / un. When a word start with a voyelle or an h use l', and adjectif like "difficile" do not need any article
