This is a statement that reflects a writer's belief about a topic , and it cannot be proved.

The correct answers are:

b. The boy killed the spider with his shoe.

In order to make a positive statement, we should remove did not from the sentence, and put the verb to kill into Past Simple tense.

c. The angry mother asks her son: „Do you think you know better than your dad?

To make a direct speech, we should convert the verbs into an adequate tense, in this case, the Present Simple tense, and adjust all the pronouns to the context.

d. Where has your father found you?

We should convert the subject of the passive sentence into the object of an active sentence.

e. We should forget these happy moments.

The past form of shall is should.

f. There won't be any trouble, will there?

In this sentence, we use the form will to emphasize the question we've made in the first part of the sentence.
