8) Identify the best 2 problem questions about things you might be observing right now. Why did Janie refuse to say "hi"? What is the effect of sunlight on the pavement outside? What enables me to take air into my lungs? When do we eat? Why am I listening to my iPad?

Explanation:

We can make this conclusion because the question is concerned about things been observed right now; so the statement;

"What enables me to take air into my lungs?" Is been observed right now since breathing is a continuous body activity that the speaker must be doing at that moment. Next, in the statement,

"Why am I listening to my iPad?" the speaker here uses a continuous tense "listening", indicating an ongoing action in progress.
