Doug had an amazing interview; therefore the company hired him immediately.

Brad had done his homework and prepared for class, so he knew the answers to all the questions asked by the teacter.

Every weekday, the students are most likely to take the bus to go to school.

Based on the sentence, we can tell that the correct answer should be a word that means "something that gets in the way" that Susan B. Anthony would have to overcome. "Obstacles" is the correct answer because it means something that opposes or stands in the way of progress.

Incorrect Answers:

"Legislation" means laws. Even though the laws of Susan B. Anthony's time were in the way of women getting the right to vote, "legislation" is a singular word that would make this sentence grammatically incorrect. The word "many" must be followed by a plural word.

"Innovation" means something newly introduced, as in the sentence, "Recent technological innovations include laptop computers, tablets, and smartphones."

A "trait" is a distinguishing feature, such as someone's personality or physical appearance, as in the sentence, "Kai has many wonderful traits, and she is most well-known for her kindness and humor."

We know that the word that goes in the blank needs to mean something like "ability to exercise for hours," so the correct answer is "endurance," which means ability to do something for an extended period of time. "Swinging," "swimming," and "jumping" all have to do with specific sports, and we aren't told that the "athletes" being discussed in the sentence play a specific sport. "Endurance" is the only word that refers to athletes in general staying in shape. 

The correct answer is "climate," which means the weather, temperature, and moisture levels experienced in a region. "Heat" wouldn't make sense because the sense describes the blank as "colder," and "humidity" (amount of moisture in the air) doesn't make sense either. "Wind" could be described as "colder," but "climate" is the better choice because one might to hear about the "climate of Wisconsin" more often than the "wind of Wisconsin," because it is the more general term.

The correct answer is "impact." In this sentence, "impact" means a strong influence over someone.  The other words do not make sense in the sentence.

The correct answer is "generosity." "Generosity" is the quality of being kind or generous. The other answer choices are not qualities people would want in friend, so none of them fit the context of the sentence.   

A prodigy is a child with extraordinary talent.  Mary-Lou is a prodigy because she is internationally recognized for her talents at a young age. 

When rules are broken, the result is often a consequence like being grounded or going to the principal's office. "Consequence" means result, and is often specifically used to refer to the results of breaking rules.
