The sentence:
" What time is the football game playing on television. "
Is a question as it is asking... what time something will start.
This means there should not be a period at the end, but a question mark instead. That is a punctuation error.
Therefore the answer is, Review your capitalization and punctuation.
The grammar is accurate as there are no misplaced modifiers.
The spelling is all accurate.
This is not meant to be a factual statement, but instead a question.
