1. Provided that the word in italics is pent-up, the correct answer is C. Stored up. It means confined, suppressed, repressed, restrained. We can also deduce this meaning from the context because this energy needed an outlet, and it found it in a rough and rowdy game of football.
2. Provided that the word in italics is millennia, the correct answer is B. Thousands of years. This word comes from Latin (mille - thousand, annus - year). We can also deduce this from the context because we know that people used to believe for many ages that Earth is flat (and not so many reasons, except for the most obvious one - it looks flat to the naked eye).
3. Provided that the word in italics is dispersed, the correct answer is C. Spread. To disperse something means to spread or distribute or disseminate it over an area, typically a wider one. We can also deduce this from the context, first and foremost the word "throughout", supported by the fact that hundreds of fish were killed. The next best option would be "leaked", but if the oil spill only leaked, it wouldn't kill so many fish.
4. Provided that the word in italics is obliquely, the correct answer is B. Indirectly. It means that Louis parked the car diagonally, or at an angle. We can deduce this from the context because it says that he passed the drivers licence test. If he parked abruptly, nervously, or quickly, he wouldn't have passed it.
5. Provided that the word in italics is scourge, the correct answer is B. Cause of trouble or pain. Scourge means menace, something that causes great suffering, but it isn't necessarily connected with disease. We can deduce it from the context because we know that rats caused great trouble, and couldn't possibly be understood as omens or signs of good fortune or harvest.
