In this situation, Jessica is indebted to Sarah for editing her paper even though it was not required for Sarah to edit it.  Therefore, Jessica compensated her by bringing her out to ice cream as a thank you for doing her the favor of editing.

Tom's sister wants to erase the comments of the morning or revoke them. In other words, she wants to rescind her comments.

The sentence implies that Scott had to become aware and comfortable with new aspects of life in his town, for they differed from what he had known. Such a process of becoming comfortable with something new is called “becoming accustomed.” Notice that the word contains the word “custom,” and the “ac” is really the “ad” prefix meaning “to or toward.” Therefore, the process of “accustoming” is (in a sense) “structuring oneself ‘to the customs’ of a given area or process.”

The implication here is that Travis “aims” at high goals. Therefore, one could say that he hopes to accomplish these tasks. Such hopes are often called “aspirations,” a word coming from the Latin for “to breathe toward.” There are English words like “despair,” that mean “without hope” but are based on a different (but very close) Latin word meaning hope. The word for “I breathe” is “spiro” and the word for “I hope” is “spero.” Latin students often learn the shortened quip, “Dum spiro, spero,” meaning, “While I breathe, I hope.”

The key word in this sentence is “tightly,” which indicates that Robert was not merely holding on with a limp hand. The best option, therefore, is “clutched” which captures this sense of direly holding on in a tight-fisted manner.

When someone is able to aid others in doing their work, particularly in making it easier, that person is said to “facilitate” the work. The word “facilitate” comes from the Latin root word for “easy,” found in related English words like “facile” and “facility.”

The sentence implies that Ashley is reading the outward signs of people’s behavior in order to reach some conclusion about their inner disposition. When someone “infers” something, he or she uses indirect evidence to come to a conclusion. Similar to how the word “transfer” literally means “to carry across,” the word “infer” means “to carry into.” (The “-fer-” portion of the word here means “to bring or carry,” from the Latin “ferre.”) An inference “carries” someone into the heart of a matter.

Although the word “navigate” often applies to one traveling on a ship, it can be extended to apply to any case of planning the route that one must take. Given that the sentence speaks of Andrew’s great knowledge of the confusing streets, the best option will be “navigate,” which indicates that he knew how to find is way around the town. The word “navigate” does come from roots for “ship,” found in “navy” and “naval.”

The general implication of the sentence is that Eric is planning to sell these items during the summer. The key qualifying word is “cheap,” which helps to eliminate the tempting answer “retailing.” When someone “peddles” something, he or she not only is said to sell it but likewise is said to be selling something that is cheap, often doing so by traveling from place to place.

We can infer that we need to pick out a word that means something like "place side-by-side" and has something to do with creating contrast. "Separating" cannot be the correct answer because the sentence refers to "the shapes' side-by-side placement." However, "juxtaposing" is a verb that means "place or deal with close together for contrasting effect," so it is the correct answer because it best fits the sentence's context.
