Present Perfect and Simple Past

​Present Perfect

• Definition: The present perfect tense is used to describe actions that started in the past but have a connection to the present. It focuses on the result or current relevance of past actions.

• Form: The present perfect tense is formed by using the auxiliary verb "have" or "has" followed by the past participle form of the main verb.

• Examples: "I have visited Paris" or "They have finished their homework."In English, verb tenses are used to indicate the time and completion of actions. Two important tenses for talking about past events are the present perfect and simple past tenses.
  

​The correct answer is "b) has passed." In the present perfect tense, we use "has" with the third person singular subject (she), followed by the past participle form of the verb (passed).

​Simple Past

• Definition: The simple past tense is used to describe actions or events that occurred and ended in the past. It refers to specific completed actions.

• Form: The simple past tense is formed by adding the past tense marker "-ed" to regular verbs. Irregular verbs have specific past tense forms.

• Examples: "I played tennis yesterday" or "She studied for the exam last night."
