Arecent article in newsweek stated that 25 percent of students entering collage read below the 10th grade level. is this statement an fact or an opinion?

Fact, it uses information to make a statement. Usually opinions contain “should or “would”

Answer( he"ll) is correct

Betray, destroy, and obey do not need to be changed to add the suffix -ed, because the "y" at the end of each word is preceded by a vowel  (so  they would be spelled  "betrayed," "destroyed," and "obeyed").

but hurry is different; it has to  be spelled "hurried" because the "y" at the end of "hurry" is preceded by a consonant.
