1) My friend would prefer (to make) a tea break.

To open the brackets using the infinitive, we need to determine the verb form that correctly completes the sentence. In this case, the verb "prefer" is followed by the infinitive form of the verb. Therefore, the correct answer is "to make." So the sentence should be: "My friend would prefer to make a tea break."

2) We expected him (to come) on time.

Again, we need to use the infinitive form after the verb "expected." The correct answer is "to come." So the sentence should be: "We expected him to come on time."

3) My parents agreed (to arrange) a picnic on Sunday.

Following the same pattern, we can see that the verb "agreed" is followed by the infinitive form. The correct answer is "to arrange." The sentence should be: "My parents agreed to arrange a picnic on Sunday."

4) Jane and Helen decided (to dive) though the water was co.

Here, the correct infinitive form should be used after the verb "decided." The answer is "to dive." Therefore, the sentence should be: "Jane and Helen decided to dive though the water was cold."

5) Our companions planned (to do) speed skiing in the Alps.

Once again, we need to use the infinitive form after the verb "planned." The correct answer is "to do." The sentence should be: "Our companions planned to do speed skiing in the Alps."

6) We were glad (to see) our new friends again.

The verb "glad" is followed by the infinitive form. In this case, the answer is "to see." So the sentence should be: "We were glad to see our new friends again."

7) The firefighters were lucky (to escape) from the burning.

Here, the verb "lucky" is followed by the infinitive form. The correct answer is "to escape." The sentence should be: "The firefighters were lucky to escape from the burning."

8) My colleagues are always eager (to help) each other if.

The verb "eager" is followed by the infinitive form. The correct answer is "to help." The sentence should be: "My colleagues are always eager to help each other if."

9) Janis used (to spend) holidays at the seaside windsurf.

The structure of this sentence is a bit different. The phrase "used to" implies a past habit or regular action. In this case, we need to use the base form of the verb after "used" which is "spend." So the sentence should be: "Janis used to spend holidays at the seaside windsurfing."

10) The dog was clever enough (not to cross) the busy street.

In this sentence, the adjective "clever" is followed by the structure "enough + infinitive." The correct answer is "not to cross." The sentence should be: "The dog was clever enough not to cross the busy street."
