The passage explains that cutting down trees in the rainforest increases the amount of carbon dioxide in the air, leading to global warming. This is supported by the fact that the burning of Brazilian rainforests alone produces 200 million metric tons of carbon dioxide a year.

Choice C is incorrect as the passage does not suggest that global warming is exaggerated, but rather highlights the harmful effects of deforestation.

B. The Electoral College is outdated and needs reform.
C. The Electoral College should be abolished.

Correct answer: B

Rationale: The correct answer is B: 'The Electoral College is outdated and needs reform.' The passage discusses the Electoral College system, highlighting its complexities and the discrepancy between the popular vote and electoral vote outcomes. It mentions the confusion and the case of the 2000 election where the popular vote winner did not become president. The main argument is that the system is outdated and requires reforms to align with modern democratic principles. Choice A is incorrect as the passage does not focus on ensuring all states have a say but rather on the need for reform. Choice C is not the main argument presented in the passage; while the passage mentions confusion, it does not explicitly call for abolition. Choice D is incorrect as the passage does not state that the Electoral College was created to favor larger states; instead, it discusses the allocation of electoral votes based on Congressional representation and population.
