Change these sentences into PAST tense a) I will work hard during the test.

b) I will sing on the stage.

c) I eat my lunch everyday

a. I worked hard during the test.

b. I sang on the stage.

c. I ate my lunch (Since it is in past tense we will drop everyday)

Hope it helps :)

the first, third, and last sentences are correct for plato.

a. unlikely

for improbable?
