Tenses

Actions completed in the past

Simple Past Tense expresses actions that were completed in the past. It uses the past form of verbs like 'walked', 'played', 'studied'. Option A describes Present Continuous, Option C describes Future Tense, and Option D describes Simple Present. Example: 'I visited my grandmother last week.'

I will have finished my work by evening.

Future Perfect uses 'will have + past participle' to show an action that will be completed before a specific time in future. Option A is Simple Future, Option B is Future Continuous, and Option D is Future Perfect Continuous. The key phrase 'by evening' indicates a deadline, making Future Perfect appropriate.

Present Perfect Continuous Tense

Present Perfect Continuous uses 'has/have been + -ing form' to show actions starting in past and continuing to present. 'Has been studying' fits this pattern. The time phrase 'for three hours' indicates duration, which is typical for this tense. Present Perfect would be 'has studied', Present Continuous would be 'is studying'.

was/were

Past Continuous Tense uses 'was/were + -ing form' to show ongoing actions in the past. 'Was' is used with singular subjects (I, he, she, it) and 'were' with plural subjects (we, you, they). Option A is for Present Perfect, Option B for Future, and Option D for Present Continuous.
