Jo: I don't think so, Sue seems 2) (study) very hard at the moment.

Explanation: In this sentence, we use the infinitive "to go" because it follows the verb "like." The verb "like" is commonly followed by an infinitive.

Tom: That's a shame! I would have liked 3) (go) out with her.
Jo: I wouldn’t mind 4) (come) with you.

Explanation: In this sentence, we use the gerund form "going" after "liked" and the infinitive "to come" after "wouldn't mind." The verb "like" can be followed by either a gerund or an infinitive, but in this case, we use the gerund to match the verb tense "liked." The verb "mind" is commonly followed by an infinitive.

Explanation: In these sentences, we use the gerund form "talking" after "should" and "must," and the infinitive "to work" after "claimed" and "hates." The verb "should" is commonly followed by a gerund, and the verb "must" is commonly followed by a gerund to show obligation. The verb "hates" is followed by an infinitive to show dislike or unwillingness.

In summary, the choice between using the -ing form (gerund) or the infinitive form depends on the verb that precedes it and the intended meaning. The verb "like" can be followed by either a gerund or an infinitive, while "should" and "must" are commonly followed by a gerund to show obligation. The verb "mind" is followed by an infinitive to express preference or willingness. The verb "hates" is followed by an infinitive to show dislike or unwillingness.
