Decide whether the sentences are written in Active or Passive paying attention to the tense. The first fast food restaurants were opened in the USA in 1916.

Solution:

• The sentence "The first fast food restaurants were opened in the USA in 1916." is in the Passive Voice.
• The structure "were opened" (form of 'to be' + past participle) is characteristic of the passive voice.
• The action of opening was done to the restaurants, not by them.
• The tense is Past Simple, as indicated by "were opened" and the specific year "1916".
