Manufacturer: “Many music players now allow you to tag your music acco

a) CD players do not recognize tags applied to songs in electronic (online or desktop) music players. -- We are not talking of CD players. Eliminate.

b) A recent survey showed that only 40 percent of consumers actually use the tagging options included with their music players. -- Maybe more will use tagging once we allow tagging per mood. Potential strengthener. Irrelevant at worst. Eliminate.

c) Music players are also used to manage other digital les such as audio books, language lessons, online classes and TV shows. -- Now this provides alternate usage of music players. Notice that the original passage calls for "removal" of other tagging options and not just "adding" in the option to tag music by mood. It's a strong tone. This answer choice gives alternate uses of music player which would need tags other than mood (possibly). Keep. Definitely a weakener.

d) Songs shared over the internet will retain any tags applied to them by the original listener. -- Not relevant. Even if the original listener correctly tags, it'll strengthen the argument. Eliminate.

e) Some listeners consider the 5-star tagging system to be limited and prefer a wider range of rating increments. -- Well the mechanics of the rating system can be discussed but it would assume that what author is saying is correct. So a potential strengthener. Eliminate.
