Task: Choose the correct answer for each sentence.

Here is the solution with explanations for each question:

---

#### 1. Our planet is so far away I sometimes think that it's (disappeared – appeared).
- Correct Answer: disappeared
- Explanation: The sentence suggests a sense of distance or remoteness, implying that the planet feels so far away that it seems to have "disappeared." The word "appeared" does not fit the context because it would imply the planet has suddenly come into view, which contradicts the idea of it being far away.

---

#### 2. I think my job is the best. Some people (agree – disagree) and don’t like it.
- Correct Answer: disagree
- Explanation: The sentence states that some people "don’t like it," which means they do not agree with the statement that the job is the best. Therefore, the correct choice is "disagree."

---

#### 3. I never tell lies because it is (honest – dishonest).
- Correct Answer: dishonest
- Explanation: Telling lies is considered dishonest behavior. Since the sentence says "I never tell lies," it implies that lying is dishonest, making "dishonest" the correct choice.

---

#### 4. I (like – dislike) going fishing. It is boring.
- Correct Answer: dislike
- Explanation: The sentence states that fishing is "boring," which indicates a negative opinion. Therefore, the correct choice is "dislike."

---

#### 5. When I can’t help anybody, I feel (unhappy – happy).
- Correct Answer: unhappy
- Explanation: If someone cannot help others, they might feel a sense of frustration or sadness. This aligns with the feeling of being "unhappy" rather than "happy."

---

#### 6. He loves living on space station because it is never (interesting – uninteresting).
- Correct Answer: uninteresting
- Explanation: The sentence uses the word "never," which negates the adjective. Since he loves living on the space station, it must be the opposite of "uninteresting," meaning it is always interesting. Therefore, the correct choice is "uninteresting."

---

#### 7. Don’t worry about the problem; it’s really (unimportant – important).
- Correct Answer: unimportant
- Explanation: The phrase "Don’t worry about the problem" suggests that the problem is not serious or significant. This aligns with the word "unimportant."

---

#### 8. I can’t answer this question; it’s (possible – impossible).
- Correct Answer: impossible
- Explanation: The sentence states that the person cannot answer the question, which implies that it is beyond their ability or capability. Therefore, the correct choice is "impossible."

---

#### 9. Her room is not neat; in fact, it’s very (untidy – tidy).
- Correct Answer: untidy
- Explanation: The sentence explicitly states that her room is "not neat," which directly corresponds to being "untidy." The word "tidy" would contradict the given information.

---

#### 10. Peter has very bad manners – he’s (polite – impolite).
- Correct Answer: impolite
