The key to solving this problem is the conjunction "even though." "Even though" means something like "although" or "in spite of the fact" so you know that the second part of the sentence must describe how the author was prevented from enjoying the steak in spite of themselves. The correct answer then is " . . . I could not eat anymore." All the other answer choices would make sense if the phrase "even though" was not included. 

The use of the conjunction "despite" tells you that the information in the second part of the sentence must be somehow opposite or surprising when related to the first part of the sentence. So, the subjects have different beliefs, but, despite this, " . . . the two girls were best friends." The other answer choices would all make sense if the word "despite" was replaced by "Because of . . . " 

The use of the word "but" suggests that whilst things are looking better now, they once were not. "But" is used to change the direction and meaning of a sentence. As in, "I want to go out, but I can't find my shoes." So, the correct answer is "She has suffered tremendously . . . " If it helps "suffered" means experienced pain and "tremendously" means deeply or intensely.

You will have noticed that these answer choices are all fairly similar. The only major difference between them is that they use different conjunctions. To solve this problem, then, you need to determine which of these conjunctions fits best. The correct answer is " . . . so he called the police." If the subject saw a crime being committed it makes sense that he would call the police. All the other answer choices are either nonsensical or would only make sense if the subject did not call the police. Additionally, "observed" means witnessed, saw.

The use of the conjunction "but" tells you that the information in the second part of the sentence must be somehow opposite or in direct contrast with the information in the first part of the sentence. All of these answer choices would be better matched with "and" except " . . . they still loved each other."

To solve this problem you simply need to determine which of these conjunctions makes sense in the context of this sentence. A "conjunction" is a word that links two parts of a sentence together. Simple examples of conjunctions include "and," "but," "yet," "however," and "because." In this example only the conjunction "and" makes sense as all the other conjunctions (except because) imply that the author would have no pets.

This is another problem where the key to solving it rests with recognizing the correct use of a conjunction. The correct answer is " . . . but still did poorly" because the word "but" is used to change the direction of a sentence to cause it to mean the opposite. As in "I am tired, but I refuse to go to sleep" or "I am thirsty, but cannot find any water." The answer choice " . . . less hard than him" contains no conjunctions, but simply does not fit the structure of the sentence.

The key to solving this problem is the use of the conjunction "but." This suggests that even though the speaker is thirsty he cannot actually have a drink. The correct answer is therefore " . . . I cannot find anything to drink." Most of the other answer choices would make sense if the conjunction was "and" instead of "but."

The key to solving this problem is the pronoun "their" this tells you that there has to be more than one subject of the sentence. If it was "My mother" then it would be "her/our" family; if it was "The father" then it would be "his" family. The correct answer is therefore "The mother and father . . . " because this reflects the plurality of "their."

The use of the phrase "but it was worth it" suggests that there must have been some cost or sacrifice involved. Only one of these answer choices reflects something costly that might still be worth it - "The dinner is expensive . . . "
