Do you have an example of the "text"? It's difficult to answer a question like this without seeing the text itself.
Main pieces of imagery can be something describing how stuff looks, smells, feels, or what it sounds like. It should create a picture in your head. So whatever helps illustrate the text for you is an example of imagery! Hope this helps!
The correct answer for this would be option B. Based on the given sentence above, the highlighted part of the sentence which is "<span>who had been to the mansion before," is called an appositive phrase. This is considered as an appositive phrase because it renames or describes the noun next to it. Hope this helps.</span>
The proper way to write the sentence would be "However, no one believed rumors about the Komodo dragon either." Since commas are used after words like "first, second, third, then, finally, however, but..." there would only be 1 comma in this sentence.
I hope this helps!!
"The Wooly Manner", Story by me.
One day there was a sheep, but not some ordinary sheep. This sheep was named Barnabuss, but the special thing was that he could sing. The other sheep in it's (pack?) got jealous, and started to make plots to murder(or assassinate) him. Barnabuss had been saving lots of coins to buy a new Home. He had met with one of his friends, whom said "I'd be happy to help you Barnabuss, after all, you saved my life".
I think you get the idea of where this is going.
