If you know the meaning of the word "ancestor," you'll be able to complete this sentence easily. Your ancestors are the relatives who preceded you in your family lineage, like your grandparents, their parents, and their parents before them. Note that this word generally refers to significantly distant relatives, so although your father came before you in your family line, he would be unlikely to be referred to as your ancestor. In any case, the only choice that includes older, direct relations is the one that involves Damian's great-grandparents, so that is the correct answer.

The key word in this sentence is "profit." "Profit" means money made from doing or selling something after costs have been accounted for. If it cost you one dollar to make a glass of lemonade and you sold that glass of lemonade for three dollars, you would make a profit of two dollars. In order to make money, the artist had to sell his work. Painting art that his clients enjoyed would be the best way to make sales and make a profit. 

If the artist painted pictures that were fulfilling, it doesn't mean his clients would want to buy them.

If the artist painted pictures that his family liked, it wouldn't necessarily please his clients, the people who buy his paintings. 

If the artist copied art that he saw in museums, it wouldn't guarantee that his clients would like the art that was in museums. 

If the artist tried a new style, it doesn't that he necessarily would be good at it and create art clients would buy.

The key word in this sentence is "humble," which means modest or not making a big deal out of your abilities or work. In this case, it makes sense that the humble owner wouldn't take credit for his work.  

Humble doesn't have anything to do with being friendly or hiring your friends.

Being humble wouldn't be the reason you discovered a way to save the company.

Being generous by giving surprises doesn't mean that you are also humble.

Humbleness doesn't make you creative or encourage you to start a new business.

Because his calculation was "inaccurate" (not accurate or incorrect), the subject would have written down the wrong answer for the question.  

We don't know if he or she would have aced the test based on that one question, but if they wrote down a wrong answer, he or she cannot have aced the test.

The student wouldn't have received full credit for his or her answer if the calculation was inaccurate. 

We don't know if the student would have passed the class or not based on one test question.

Having the wrong calculation wouldn't cause the student to review the section. He would be reviewing the section to check for errors. 

The only information that we are given about this class is that it "emphasizes," or strongly focuses on, individual study. In other words, the students must be encouraged to learn about the subject matter in their own way. We are looking for an answer that describes a flexible, personalized approach, not a strict cookie-cutter teaching style. Of the choices here, the only one that works here is the one about helping students find their own specific interests.

What do we know about the team captain? Only that he or she "never seemed to become fatigued." To answer this question, the first helpful piece of information to consider is the meaning of the word "fatigued," which simply means tired or exhausted. In other words, the team captain never seemed to get tired. However, a vital clue is the word "even" at the beginning of the sentence. Here, "even" implies that everyone including the team captain must've reacted to the three-hour practice in the same way, specifically one that would be unusual for the captain him- or herself. The only sensible answer is "stop and rest for a few minutes," an activity that would be remarkable for someone who rarely became tired at all.

For this sentence, finding the correct answer depends on understanding the word "although." This term is a conjunction that means even though, implying that Julia had a certain opinion in spite of Evelyn's preference for plastic. Because of this, we know that Julia must not favor the use of plastic for the project. However, be careful not to miss the final words "did not"! We're looking for something that Julia does not believe. Our answer is clear—Julia most likely would not agree with the idea that plastic was "more durable than metal."

Proper completion of this sentence relies on understanding the meaning of a single word: "invincible." An "invincible" team is unbeatable or indestructible; in other words, they must always win their games, and likely decisively. Of the given choices, a "twenty-point victory" is the only result such a team would have achieved. You may have been tempted by another choice, "mediocre performance," if you did not know the meaning of "mediocre"! However, that adjective means okay or average, and therefore does not fit with the extremely good result we would expect here.

Given that the second part of the blank describes the fact that Rebecca's mother needs a helping hand, it is logical that the blank preceding it should relate to Rebecca's capacity to help her mother. The only phrase that relates to this is the fact that Rebecca helps with the house chores, which is work that her mother might otherwise have to do alone.

The sentence tells us that Alicia speaks to her friends in a way that makes them feel bad. Thus, the blank should be occupied by a phrase expressing something negative. The phrase that accomplishes this best is "in a harsh tone of voice," which is the correct answer.
