No-one even noticed when I got home. They _______ the big game on TV.

Here's the answer and explanation: The best answer is were watching because it correctly uses the Past Continuous tense to describe an ongoing action at the time the speaker arrived home. * were watching is the correct answer. * watched is incorrect because it implies a completed action. * had watched is incorrect because it implies an action completed before another past action. * had been watching is incorrect because it suggests a prolonged action that might have started before and continued until the speaker arrived home, which doesn't fit the context as well. So, the correct sentence is: No-one even noticed when I got home. They were watching the big game on TV.
