Answer: B) the time limitations preventing African girls from attending school.
Step-by-step explanation:
From this excerpt we can infer that owning a bike has changed Lewanika's life drastically. The commute that once took her a whole hour now takes only 20 minutes. She has enough time to finish her chores before heading to school.
However, the excerpt makes it clear that the same does not happen to many girls. They are often late for school due to their chores, and the commute is usually too long. Attending school becomes difficult, if not impossible, under such conditions.
