To complete the tasks, I need to see Passage 1. Since the passage is not provided in the image, I can't directly answer the questions or fill in the blanks. However, I can guide you on how to approach these tasks.

### Task 1: Choose the best Option to fill in the blanks in Passage 1

For questions 8, 9, and 10, you need to choose the correct pronouns and verbs based on the context of the passage. Here are some general tips:

- **Question 8 [514046]**: Look for the subject of the sentence to determine the correct pronoun (me, them, him, her).
- **Question 9 [514047]**: Identify the subject to choose the correct form of the verb "to be" (are, is, am, be).
- **Question 10 [514048]**: Again, look at the context to choose the correct pronoun (me, him, her, them).

### Task 2: Read Passage 1 and answer the questions

- **Question 1 [514049]: How old is Paul?**
- Look for a sentence in the passage that mentions Paul's age directly.

- **Question 2 [514050]: What course is the hardest for him?**
- Identify any sentences where Paul talks about his courses and mentions which one he finds the most difficult.

- **Question 3 [514051]: How many students share the house with him?**
- Find information about Paul's living situation and count the number of students mentioned.

If you can provide the text of Passage 1, I can help you fill in the blanks and answer the questions accurately.
