On my friend’s farm, they . . . . . . . . an alarm clock because the cockerel . . . . . . . . at five o’clock every morning without fail.

The correct answer is: A. don’t need/crows

The cockerel crows at five o’clock every morning without fail. This means that the cockerel is a reliable source of waking up time, and the people on the farm don’t need an alarm clock.

The other options are incorrect because they do not accurately reflect the situation.

• Option B, haven’t needed/was crowing, is incorrect because it implies that the cockerel used to crow at five o’clock every morning, but no longer does.
• Option C, won’t have needed/has crowed, is incorrect because it implies that the cockerel will have crowed at five o’clock every morning in the past, but will not do so in the future.
• Option D, wont need/is crowing, is incorrect because it implies that the cockerel is currently crowing, but will not do so in the future.
• Option E, didn’t need/will crow, is incorrect because it implies that the cockerel did not need to crow in the past, but will need to do so in the future.
