Put the verb in brackets into the past simple or the past continuous. We ... (watch) television the whole evening yesterday.

The correct answer is 'were watching'. Here's why: The sentence describes an action that was in progress for a period of time in the past ('the whole evening yesterday'). This indicates the use of the past continuous tense. Past Continuous образуется с помощью вспомогательного глагола *to be* в прошедшем времени (was/were) и основного глагола с окончанием *-ing*. * 'We' is a plural pronoun, so we use 'were'. * The verb 'watch' becomes 'watching' in the past continuous. Thus, the complete sentence is: 'We were watching television the whole evening yesterday.' Ответ: were watching
