Question

mom baked _____ cake last night ___ cake was delicious ( use the article )​

Answer 1

Answer:

Mom baked a cake last night. The cake was delicious.

Answer 2

Mom baked a cake last night. The cake was delicious.

In the first blank, we use 'a' because a specific cake isn't being explicitly mentioned. It refers to any cake, so we use 'a'.

In the second blank, we use 'the' because the cake we are mentioning is specific and has been referred to already. The cake used is the cake that was mentioned in the first sentence, which is Mom baked a cake last night.
