The answer is A. the tulips were bright slashes of color like a child's crayon drawing.
No, the sentence given:
_________________________
"<span>i came home late; therefore, i didnt see aunt matildia" — is NOT punctuated correctly.
____________________________________________
The word: "didnt" should be replaced with: "didn't" (note the added "apostrophe")—or rewritten as two word: "did not".
Furthermore, there should be a "period" at the end of the sentence.
___________________________
As far as other grammar errors are concerned, the second instance of the use of the personal pronoun, "I"—is incorrectly written in the lower case: "i"—and should be replaced with the capital letter, "I". Furthermore, "</span>aunt matildia" should be rewritten with a capital letter "A" replacing the word: "aunt" [the word: "aunt" should be changed to "Aunt"], and the name: "matildia" should be rewritten with a capital "M" replacing the name: "matildia" [the name "matildia" should be replaced with "Matildia"]. Also, if "Aunt Matildia" is, in fact, really spelled that way, than the spelling of the name should be retained. On the other hand, if the aunt's name is actually spelled: "Mathilda"—or some variant, then the proper spelling should be used—and the first letter should be capitalized.
