Sentence 2:

Sentence 3:

Sentence 4: In my opinion, scoring well on it is all about how I prepare.
I can answer questions #1 and 3, as the question #2 is incomplete.
1. The correct answer is B. <span>the time limitations preventing African girls from attending school. The chores African girls had were difficult, and it made their lives more complicated than their brothers'. The author confirms that, but it isn't the focal point, as we can see from the last 3 sentences. Those chores resulted with girls needing more time to arrive at school, and the bicycles solved this problem, making their lives easier.
3. The sentence that should be removed is </span><span>5 There are always jealous people who selfishly do not like to see others succeed, and bicycle racing was no different. Words such as "jealous" and "selfishly", as well as subjective assessments of other people's behaviors, aren't an objective way to tell something. All the other sentences in this summary deal with facts, more or less confirmable.</span>
