Choose the correct sentence in Present Perfect: "We ... a clean-up in the park."

Present Perfect Tense

Present Perfect tense is used to describe an action that happened at an unspecified time in the past, or an action that started in the past and continues to the present. It is formed with 'have/has' + the past participle of the verb.

The subject of the sentence is 'We', which is a plural pronoun. Therefore, we need to use 'have' with the past participle of the verb 'organise'.

• The past participle of 'organise' is 'organised'.
• With the plural subject 'We', we use 'have'.
• Thus, the correct form is 'have organised'.

The complete sentence is: "We have organised a clean-up in the park."

Answer: have organised
