This sentence is describing someone who has very high moral standards for himself or herself. This means that he or she is not merely an agreeable personality. No! He or she has a virtuous character, one that is ready to do good at any time. This moral aspect is needed for the sentence to be completed correctly.

Since Peter apologizes for his tendency to yell at others, we can rightly guess that he is not very proud of this character trait. It doesn't make sense to say that he is "hateful of it." We can say that he is embarrassed by it—or, is ashamed of it. 

It seems that Laura is trying to encourage her son to be more positive. We don't know if he is being angry or impulsive (or really anything else). All that is indicated is that Laura wants him to look for the best in every situation. Therefore, his attitude must be rather negative. A negative person looks for the worst thing in every situation. It actually comes from roots that mean "no"—as though the negative person always says "no."

You might think that this sentence is saying that the turkey was the common or traditional thing for the meal. It doesn't really indicate that at all. Perhaps the person eating the meal can only eat turkey meat. In that case, it is not really because of tradition that it is needed. Instead, the point of this sentence is that although other things don't really matter, the turkey is "essential."  Another way of saying this is that it is something that you just can't go without.

The most important clue in the sentence is the final clause. This means that there is a contrast being discussed here. The army went from losing to winning. Therefore, we can say that it was finally "victorious," at least in one very important battle.

The scheme used to trick their parents every night was well thought out and detailed or elaborate. They needed to think up several ways to delay the process of going to bed early.

The second part of this sentence tells us that the football team treats their opponents with respect, even after a tough loss. This immediately eliminates two choices: since the players are being nice, they clearly are not "reacting with anger at their loss," and they are shaking hands, not "ignoring the other players." Additionally, the statement that "they celebrate afterwards with a good meal" is certainly possible, but not confirmed by the rest of the sentence. The answer is that they "display good sportsmanship," which means they acted honorably (they weren't "sore losers") and played fairly.

To complete this sentence, you need to know the meaning of the word "ambiguous." When instructions are ambiguous, they are not straightforward or easy to understand; instead, they have multiple possible meanings. Kaitlyn would likely be confused by instructions like these, and might need to ask her teacher for a better explanation. She would not "easily complete the homework without confusion" or immediately "understand the project," and we have no way of knowing whether these instructions would prevent her from working with a group.

We know that Brentan wishes he had a younger brother, and that he does something on weekends that corresponds with this feeling. This weekend activity is probably related to young children; otherwise, Brentan's wish for a little sibling wouldn't be relevant. Having friends "a few years older" is backwards; we have no reason to think that Brentan wants older peers in his life. Similarly, he would not want to "avoid small children" if he wanted a little brother, and "shopping with his mother" isn't related to the rest of the sentence. The only sensible answer is that he volunteers with a sports team for young children.

With this sentence completion, as with most others, the first step you should take is to quickly scan the sentence for key words. Here, the word "although" is immediately obvious. We are told that Martin used to be unable to play basketball, but this word "although," which implies contrast, hints that the situation is now different. So, the answer choice that states that Martin's "knee still hurts him nearly every day" is incorrect because it does not contain this contrast. The same is true with the choice regarding medical bills; if Martin is injured, expensive medical costs would be unsurprising. Finally, the statement about the class trips is irrelevant. Our answer is clearly the choice stating that although Martin couldn't play before, he was now healthy enough to "start as center tonight."
