1. The teacher told her pupils to learn twenty irregular verbs.
Explanation: "Regular" means happening on a consistent or predictable basis. The adjective is used to describe the verb, implying that there are some verbs that are not consistent or predictable in their conjugation or usage. The negative prefix "ir-" is added to indicate the opposite, meaning that the verbs in question are not regular but rather irregular.

2. Mrs. Brown is really impolite. She never wants to talk to anyone.
Explanation: "Polite" means having or showing good manners and respect for others. The negative prefix "im-" is added to indicate the opposite, meaning that Mrs. Brown lacks good manners and respect, making her impolite.

3. Susan does not want to be insensitive to her friends.
Explanation: "Sensitive" means being aware of and responsive to the feelings of others. The negative prefix "in-" is added to indicate the opposite, meaning that Susan does not want to lack awareness or be unresponsive to her friends' feelings. Therefore, she does not want to be insensitive.

4. Adam is so impatient. He never wants to explain things twice.
Explanation: "Patient" means being able to tolerate delays, problems, or suffering without becoming annoyed or anxious. The negative prefix "im-" is added to indicate the opposite, making Adam lack tolerance and become easily annoyed or anxious. Therefore, he is impatient.

5. These window locks are ineffective and expensive.
Explanation: "Effective" describes something that is successful in producing a desired result. The negative prefix "in-" is added to indicate the opposite, meaning that the window locks are not successful in producing the desired result. Therefore, they are ineffective. Additionally, "expensive" means having a high price or cost associated with it. No negative prefix is needed as it already conveys a negative meaning, indicating that the window locks are costly.

6. John said he was sorry, but they were unsure that he was sincere to tell people that you don't like their clothes.
Explanation: "Sincere" means genuine, honest, and without deceit. No negative prefix is needed in this sentence as it already conveys a positive meaning. John's sincerity is being questioned, implying that he might not genuinely express his dislike towards people's clothes.

7. It is very informal to dress in comfortable clothes.
Explanation: "Formal" means conforming to or following established rules, customs, or conventions, especially in a ceremonious way. The negative prefix "in-" is added to indicate the opposite, meaning that dressing in comfortable clothes does not adhere to established rules or conventions, making it informal.

8. These parties are almost always irregular in their dress code.
Explanation: No negative prefix is needed in this sentence as "regular" already conveys a positive meaning. The parties are described as having an irregular dress code, meaning that the dress code is not consistent or predictable in its expectations.

9. They were sitting in a very loyal position.
Explanation: "Loyal" means having or showing allegiance, faithfulness, or commitment. No negative prefix is needed in this sentence as it already conveys a positive meaning. Their sitting position is described as loyal, implying that they are sitting in a committed or devoted manner.

10. Mr. Black thinks it is very disloyal of Tom to think he can do just what he likes.
Explanation: "Loyal" means having or showing allegiance, faithfulness, or commitment. The negative prefix "dis-" is added to indicate the opposite, meaning that Mr. Black finds Tom's behavior lacking allegiance or faithfulness. Therefore, he considers it disloyal.
