Please help me make sentences at least 9 words long each with these words. One word in each sentence. Also use the part of speech provided.

Thanks for helping. If you can't get all the sentences, a few or just 1 would be helpful. I will pick the person w/ the most sentences and best sentences for best answer.

Answer 1

I would not accost a stranger, except in an emergency situation.

Please put the statue in the small niche on the south wall.

He endeavored to succeed; but he discovered his efforts were in vain.

Just because I cannot attend that doesn't preclude the necessity for the meeting.
