Tiger, penguin, wolf and dolphin. Apply for me.
The correct answer is 'phenomenon'. A phenomenon is any event that is observable, however common it may be.
Diction and figurative language can impact an author's tone and characterization because they can make the story seem more real if everything is working well together, or they can keep the reader from connecting to the work if the choice of words and use of language clashes with the tone the author is trying to convey.
Hello! Gramatically, let's look at each choice-
(a) says: Mrs. Anderson flies to Sweden tomorrow her plane leaves at 2:00 P.M.
This can't be right, because it's a run-on sentence! If someone were to say this outloud, it would sound as if someone wasn't "taking their time"!
(b) says: Mrs. Anderson flies to Sweden tomorrow, her plane leaves at 2:00 P.M.
This one looks correct. It has a comma which adds a pause. It also connects both statements made in the sentence.
(c) says: Mrs. Anderson flies to sweden tomorrow, and her plane leaves at 2:00 P.M.
This one wouldn't be correct because its listing ideas with "and" in between. It's as if the speaker is saying "she does this and this and that and that..."
So your best choice would be B.
