The question asks to choose the correct verb tense to complete the sentence, which indicates an action that will be finished by a specific future time. This requires understanding the use of future perfect tense.

The sentence describes two past actions: reaching the station and the train's departure. To correctly convey that one action happened before the other in the past, we need to use the past perfect tense for the earlier action and the simple past tense for the later action.
Correct Option: C) had left — This option correctly uses the past perfect tense ("had left") to indicate an action that was completed before another past action ("we reached the station"). This is the appropriate tense for describing a sequence of past events where one precedes the other.
The question requires choosing the correct verb tense to complete the sentence, indicating an action that was in progress when another action occurred. This typically involves using the past continuous tense for the ongoing action and the simple past tense for the interrupting action.
Correct Option: D) "was eating" is the correct choice. The sentence "I was eating my dinner when he arrived" correctly uses the past continuous tense to describe an action in progress in the past, which was interrupted by another past action (his arrival).
The sentence describes a habitual action, indicated by the adverb "always". For habitual actions in the present, we use the simple present tense. We need to select the correct form of the verb "to lose" that agrees with the third-person singular subject "He".

The question requires us to choose the correct verb tense to complete the sentence "I ___ this song before." The phrase "before" indicates an action that has occurred at some indefinite time in the past and has relevance to the present. This calls for the use of the Present Perfect tense.
C) have heard — This is the correct option. The Present Perfect tense ("have heard") is used to describe an action that happened at an unspecified time in the past and has a connection or relevance to the present. The word "before" signals this usage perfectly, indicating a past experience that is still relevant.
