How is the word pioneer connotative? select all that apply.

There has to be a period in between "at" and "there" in the first sentence as they are two different sentences. the sentence "some are brown. some eggs are blue." may be phrased better as, "some eggs are brown while some eggs are blue." lastly, there should not be a question mark at the end of the word "delicate" since the last sentence is not a question. rather, it should be a period instead.
