As someone who is naturally warm, he probably thought the house was just about the same. Therefore, the implication is that he didn't even think that others might be cold. That means that he likely did not realize it. He was not aware of it.

The use of the word "but" is crucial to solving this problem. "But" is used to change the direction of a sentence, to cause it to mean the opposite, so in this instance if the girl is twenty minutes late she must usually not be late.

Additionally, "dogged" meansdetermined and hard-working; "delayed" meanslate, halted, paused; "miserable" meansvery sad; "perilous" meansdangerous.

The key to solving this problem is the use of the word "although." "Although" is used like "however," "yet," and "but" to introduce an opposite or contrasting idea. So, most of these answer choices would be better served with the conjunction "and" which is used to continue an idea. The correct answer is therefore " . . . I could be wrong." The author is unsure of themselves and this is reflected in the words "think" and "although."

To solve this problem you simply need to recognize which of these conjunctions makes the most sense within the context of this sentence. The correct answer is " . . . due to terrible weather."

Additionally, "favorable" meansadvantageous, offering some benefit.

The use of the conjunction "despite" tells you that the day in question did not live up to the "hype" (excitement). The day must therefore have beendevoid of action, boring and normal.

Additionally, "giddy" meanslight-headed and dizzyorexcited; "optional" meansnot required, a choice; "insolent" meansrude and obnoxious; "degraded" meanstreated with disrespect and made to feel worthless.

The sentence talks about how the world is changing and complex. This implies that people rarely "settle" on one political opinion. While this means that people may not be happy with their opinions, we really can't say much about happiness, given our clues. We must be as vague as the sentence itself is. Therefore, the best option is merely "certain." To be "certain" is to be sure and settled about something. This is as much as you can say for this sentence.

The sentence implies that the image in the window was not what it appeared to be. For this reason, the best option is "illusion." When something is an "illusion," itappears to be one thing while being another. Often, we speak of "optical illusions." These are just a particular kind of illusion, namely one that we see with our eyes. (Indeed, in this sentence, the illusion is optical!)

The key thing to notice is the fact that the nation has changed "from" being a foe "to" its current status. Thus, you should pick an option that best expresses this contrast to being a foe. It is for this reason that "ally" is the best option. An "ally" issomeone who has friendly relations with another group. Thus, to go from being a foe to being an ally means that someone goes from being an enemy to being a friend. This is the best option among those given.
