Rigorous means to be very strict and instense. Given that Rebecca hasn't missed a morning run in two years, she is very diligent and disciplined. The word that best fits the sentence to describe her in this way is rigorous. While ruthless means determined, it has a combative connotation, which is not appropriate for the sentence. 

This sentence contains multiple context clues, any of which can be used to narrow down the answer choices. First, Rachel's plan was "outlandish," meaning it was ridiculous or at least strange. Even more helpful is the end of the sentence, where we're told that the plan was "not __________ enough" to use. So, we're looking for a positive quality that Rachel's plan must have been lacking. This allows us to eliminate "pointless" and "inadequate," which would both be negative qualities in a plan. Similarly, the committee would be unlikely to reject the proposal for not being "extravagant" enough, especially since we already know that it was "outlandish." "Compatible" refers to two things that can work together well, or two people that can get along together well, and since no two things are being compared in the sentence, "compatible" cannot be the correct answer. The final answer remaining is "sensible," which fits perfectly in this sentence.

The key clue provided by this sentence is the fact that Mr. Jones goes to the same bagel shop every morning. Therefore, it can be inferred that he is a lover of "routine," which is the correct answer.

Here, the sentence plants the clue that because the window is very dirty, it is not possible to see through it. Thus, the best word to describe the window would be one that indicates its lack of clarity. "Opaque" means cloudy and nontransparent, so it is therefore the best word to complete the sentence. While "obscure" may seem like a potentially correct answer choice because the window is "obscuring" Gina's view, the window itself is not "obscure," which here means hidden or unknown. Similarly, since Gina cannot see through the window at all, we cannot accurately call it "translucent," since something translucent still lets some light through and can thus still be seen through somewhat.

You would hurt yourself if you jumped into a pool and there was not much water there. When water is not deep, it's called “shallow.” “Supreme” means the best.

Because the hot air balloon went up into the sky, we can pick out “ascended” as the correct answer. The word “dismissed” means ignored an idea or sent away; “reported” means spoke, wrote, or told about.

Gina is described as wearing "a long black dress," which is very formal, as well as "a serious expression." These circumstances indicate a distinct lack of playfulness. "Somber" means serious and lacking in humor. It fits the context of the sentence well, and is therefore the correct answer.

Here, the sentence describes a princess who is pampered and is able to do as she pleases. "Leisure" refers to the ability to do whatever one wants with one's time, so a "life of leisure" would be one where one has no commitments such as a job. So, "leisure" is the answer choice that best fits the sentence's context.

Classes usually focus on ideas or "concepts." This differs from "ambitions" (goals or things people want to achieve); "procedures," (systematic ways of doing things); "objects" (aims of plans or things); and "plans" (definite, often multi-step ideas about how to deal with or accomplish something).

“Content” is the correct answer because it means satisfied with the way things are.
