some people think that listening to country music is one of lifes greatest pleasures. others would much rather jam out to hip - hop or rap music. and, of course, there will always be those who think rock music is king. even though most people have the opportunity to listen to many types of music, they usually end up with a favorite. no one knows exactly why people have particular music tastes. of course, the environment has something to do with it. if a girls big brother loves hip - hop, then she will often hear it. she may end up liking it, or she may end up hating it. people often say, \there is just no arguing taste.\ in the case of music, this is definitely true.

Explanation:

1. For question 14: The sentence that directly shows sniffer dogs are excellent at detecting drugs is the one stating they can pick up even the faintest drug scents. Option B is incorrect (receptors are longer, not smaller), option C only states where they work, and option D is about human noses and taste, irrelevant to the dogs' detection ability.
2. For question 15: The passage focuses on sniffer dogs, their superior sense of smell, and their use in detecting drugs/firearms. Options A, B, and C are only minor details, not the main topic.
3. For question 16: The passage discusses different people's preferences for music genres and mentions how environment may influence these tastes, centering on varied musical preferences. Option A is incorrect as no genre is called the best, option B is a small example, not the main topic.

Answer:

1. A. They can pick up the lightest scent of drugs or firearms.
2. D. drug sniffing dogs.
3. C. different musical tastes
