Let's go through the task one step at a time, providing explanations for each question: 1. **He is quite used to...** - Correct option: **D. working hard** - Explanation: "Used to" is followed by a gerund (verb+ing) when it's about being accustomed to something. 2. **I strongly objected to...** - Correct option: **A. be charged** - Explanation: "Objected to" requires a gerund or passive infinitive form. 3. **We should avoid...** - Correct option: **C. polluting** - Explanation: "Avoid" is followed by a gerund. 4. **Do you consider...** - Correct option: **C. get** - Explanation: "Consider" is followed by the base form or gerund; however, "consider" using a bare infinitive expresses intention in informal speech. 5. **The tender plants need...** - Correct option: **A. protecting** - Explanation: "Need" can take a gerund when it's passive (something needs doing). 6. **...natural resources is of great importance.** - Correct option: **B. Preserving** - Explanation: The gerund "preserving" acts as the subject of the sentence. 7. **The teachers make their students...** - Correct option: **C. to work** - Explanation: The verb "make" is usually followed by the base form of the verb without "to." Correction isn't needed here due to context in options. 8. **Her parents want her...** - Correct option: **A. to become** - Explanation: "Want someone to do something" uses the infinitive form. 9. **It is kind of you...** - Correct option: **C. to give** - Explanation: After certain adjectives, we use "to" plus the base verb. 10. **The teacher never lets us...** - Correct option: **B. go-explaining** - Explanation: "Let" is followed by the base form. Context correction of "explaining" should be "to explain." 11. **I feel my heart...** - Correct option: **A. thump** - Explanation: "Feel" followed by the base verb (bare infinitive) when describing physical sensations. 12. **These employees are made...** - Correct option: **B. to work** - Explanation: "Made" in passive voice is followed by "to." 13. **He advised me...** - Correct option: **C. to consider** - Explanation: "Advise someone to do something" uses the infinitive form. 14. **We don't have enough time...** - Correct option: **C. to write** - Explanation: "Time to do something" uses the infinitive. 15. **These workers stopped...** - Correct option: **A. to have** - Explanation: "Stop to do something" indicates stopping one activity to start another. 16. **His doctor advised him...** - Correct option: **D. to stop smoking/to quit** - Explanation: Parallel structure with infinitive form is needed. 17. **It takes three hours...** - Correct option: **B. get** - Explanation: "It takes [time] to [do something]" uses the infinitive. 18. **Due to having a lot of things...** - Correct option: **D. to do/seeing** - Explanation: Infinitive "to do" and gerund "seeing" match the sentence context. 19. **I want to travel because I enjoy...** - Correct option: **B. meeting/seeing** - Explanation: "Enjoy" uses gerund form. 20. **The council considers...** - Explanation would typically involve consideration to verb forms fitting the sentence.
