Question ID:PT54 S2 Q24 Passage:There are 1.3 billion cows worldwide, and this population is growing to keep pace with the demand for meat and milk. These cows produce trillions of liters of methane gas yearly, and this methane contributes to global warming. The majority of the world's cows are given relatively low-quality diets even though cows produce less methane when they receive better-quality diets. Therefore, methane production from cows could be kept in check if cows were given better-quality diets. Stem:Which one of the following, if true, adds the most support for the conclusion of the argument? Correct Answer Choice:AChoice A:Cows given good-quality diets produce much more meat and milk than they would produce otherwise. Choice B:Carbon and hydrogen, the elements that make up methane, are found in abundance in the components of all types of cow feed. Choice C:Most farmers would be willing to give their cows high-quality feed if the cost of that feed were lower. Choice D:Worldwide, more methane is produced by cows raised for meat production than by those raised for milk production. Choice E:Per liter, methane contributes more to global warming than does carbon dioxide, a gas that is thought to be the most significant contributor to global warming.
