@Stas1973 I think in a different context that would suffice, but my first post indicates the 'tricky' nature of the use of the word 'sport' in colloquial terms.

All of the above are helpful. Its not uncommon that one of the modes of explaining leave open some questions. Sometimes when taken together, they make more sense and strengthen some connections. All three are helpful. I would say that I prefer the video the most often; the elaboration of key points in the video/audio format makes tough questions easier to grasp. The discussion boards also offer some guidance as well.

Definitely a lvl5 question.

AC C does actually support the conclusion but not as strongly. AC C supports the first sentence that leads to the rest of the experiment, if it were not true, then it would weaken the argument. AC C is not the answer bc in the experiment, the psychologists only LISTENED to the recordings. There would be no way to SEE the displayed emotion that AC C offers as support.

AC D offers a full explanation of how the emotion effects the physiology of the body while singing.

The author makes 2 conclusions, AC C and AC E. C is a sub conclusion that leads to the final conclusion of E.

Drill baby Drill

@lexxx74569 AC B he needs to know to fall into the premises of the conclusion. AC B is arguably an answer bc how is he to 'benefit' if he does not know to improve?

Any advice for an approach without diagraming?

Tricky tricky. Are there any sports that you would not be 'competing' against any other athlete? Even individual sports, you are competing against another athletes record, score, time etc.

@LowriThomas please elaborate what it has to be before last year. at 2.33 in the video, he explains that its possible to sell the trucks the same year as the purchase

Is it correct to say that this mistakenly uses the necessary condition as the sufficient condition?

Does anyone have suggestions for thinking through this problem quickly. The video makes sense, but we don't have 4minutes to discuss and draw this out.

@gonewiththewind thank you, this was more helpful than the video

reasoning skills = general understanding

how does 'other than trees' play any part in logic?

@Kevin_Lin thanks

@Kevin_Lin So am I correct in understanding that we are not using the 'and' as a biconditional?

I really appreciate all that you have laid down in this post.

5/5 less go!

@MallikaMalhotra that could be a shot in the dark and risky

@Kevin_Lin ok thank you

I came to the correct answer but it is not clear why 'x REQUIRES y' means that x is sufficient. Why is x not sufficient? why not: Motive ---> Change?

1: This actor is not mentioned in another play. Other plays are not mentioned. Similarly: what reason do we have to believe that a firefighter in the adjacent town owns a copy. We don't. Its Reasonable to assume that the person with these traits would be an actor not a firefighter.

A is very reasonable as an AC. College is advertised as for both expanding academic interests AND discovering new ones. It also functions as such.
