Answer 1

My mother bought bread and two pounds of butter.
What were you doing around four o'clock yesterday afternoon?

"bread" は不可算名詞なので冠詞 "a" は不要です。
文の時制を過去形に合わせるため"are" ではなく "were" が適切です．

①My mother bought [a piece of] bread and two pounds of butter.
※日常生活での買い物では、a bread は可能ですが、書き言葉の文では a piece of bread(パン一個)が正式な表現
②What [were you doing](過去進行形) around four o'clock [yesterday afternoon]?
昨日の午後4時頃、あなたは何をしていましたか？

参考にしてください。
