The correct answer is (D).

According to the Exterior Angle Theorem, the measure of the exterior angle of a triangle is equal to the sum of the measures of the remote interior angles.
In this question the exterior angle is ∢BCD, therefore it equals the sum of ∢ABC and ∢BAC:
60° + α = 145° → α=85°

Exterior Angles
An exterior angle is formed by extending one of the sides of the triangle. The angle formed between the extended side and the other side is the exterior angle:

Alternative Solution
This question can also be solved using the inner angles of the triangle. ∢ACB and ∢BCD are supplementary angles and therefore they add up to 180°. Thus:
∢BCD + ∢ACB = 180° → 145° + ∢ACB = 180° → ∢ACB = 35°
Looking at the triangle ∆ABC you now have two angles whose value you know, and the missing value of α. In a triangle the angles add up to 180°, therefore:
∢BAC + ∢ABC + ∢ACB → α + 60° + 35° = 180° → α = 85°

The correct answer is (A)

First, set up the division:



Take the first pair of numbers and divide by 14. 14 divides into 63 four whole times. Write this four above the 63. Then, subtract the four batches of 14 (4 x 14 = 56) from the 63 to find the remainder.
4 x 14 = 56.
63 – 56 = 7.
The remainder of that division is seven.



To do the next division, bring down the next number in the dividend, which is 9.



Now, divide 79 by 14. 14 divides into 79 five whole times, as 5 x 14 = 70. Write the 5 above the 9.
To find the remainder, subtract 70 from the 79. Therefore, the remainder is 9.



Once again, bring down the next number in the dividend, the 8. Then, divide 98 by 14. 14 divides into 98 seven times exactly. Write the 7 above the 8.



After the last division, there are no remainders, as 14 is a factor of 98. Therefore, the correct answer is 457.

The correct answer is (D).

To solve this problem, first find Daniel's age. Daniel's father's age is four times greater than Daniel's age. Therefore, to find Daniel's age, divide his father's age by 4: 48 ÷ 4 = 12. Daniel's age is 12, and next year he will be one year older, meaning he will be 13 years old. Therefore, the correct answer is (D).

The correct answer is (D).

Vivid description or imagery uses descriptive language to give the reader a strong sense of how something looks, sounds, smells, feels, or tastes.

Answer (D) is correct because the sentence creates a vivid description by describing the stones as smooth and flat and that when they are skipped they make rippling patterns. This gives the reader a sense of what it is like to touch the stones and watch the patterns they make in the water.

Answer (A) is incorrect because the planes are not described vividly. Rather, the sentence just describes the planes as loud and annoying. Here is an example of a more vivid sentence about the same topic:

Planes blasting overhead make it hard for us to think.

Answer (B) is incorrect because the plankton are not described vividly. Rather, the sentence just describes them as tiny and essential. Here is an example of a more vivid sentence on the same topic:

Without plankton so tiny you can't see them without a microscope, whales and other giant ocean creatures could never survive.

Answer (C) is incorrect because the National Mall is not described vividly. Here is an example of a more vivid sentence on the same topic:

While the National Mall might sound like a big air-conditioned building filled with glitzy stores, it's actually a leafy park filled with austere monuments and memorials.

The correct answer is A.

Alliteration is when multiple words appearing close together begin with the same sound. In the above sentence, the words “spend,” “Spencer,” and “circle” all begin with the same consonant sound, even though they do not all begin with the same letter. “Simile” is incorrect. A simile compares different things figuratively by stating their likeness, usually using words such as “like” or “as.” The sentence uses a metaphor by comparing Spencer’s friends to wolves, but it does so by saying that they are wolves, not by saying that they are like wolves or that they behave as wolves do. It is, therefore, only a metaphor, not a simile, which is not one of the answer choices. “Oxymoron” is incorrect. An oxymoron is a seemingly contradictory phrasing of something that joins two opposing words to reach its meaning. One might think that “incredibly rude” is an oxymoron because the word “incredible” has good connotations, whereas the word “rude” is generally negative, yet their definitions pose no actual contrast. To say that something is incredibly [blank] is merely to say that the degree to which it is [blank] is incredible, meaning that it is unusual or extraordinary how [blank] it is. Or, in simpler terms, it means that it is very [blank]. Therefore, it is not oxymoronic to say that someone is rude to an unusual degree. An example of an oxymoron using the word “incredibly” could be “incredibly ordinary.” What this essentially means is that it is very ordinary, yet it accomplishes this meaning by stating that it is unusual how usual it is, or extraordinary how ordinary it is. These are words with direct contrast. “Onomatopoeia” is incorrect because it refers to words that mean the sound that they make, such as “buzz” or “boom,” and there are no words like this in the sentence. “Foreshadowing” is incorrect because it refers to when later events are hinted at, and we are only looking at one sentence, so there are no later events to be foreshadowed. “Personification” is incorrect because it refers to giving human attributes and abilities to non-human entities, and this is not done in the sentence.

The correct answer is A.

A pronoun is a word that refers to a specific noun in a given context, and its antecedent is the word that is being referred to. Vague pronoun use is when it is unclear what the antecedent is, as there are multiple fitting subjects or objects that could be what the pronoun in the sentence is referring to. In the sentence in option A, the word “which” is a relative pronoun referring to something that “was the reason [Callie] was late for work.” It is unclear, however, which antecedent it is referring to—the fact that she “styled her hair in a French braid,” or “the heavy rain outside.” That is why it is considered vague pronoun use. (Note: There is no noun present in the first part of the sentence that is serving as the antecedent to the pronoun “which,” yet the pronoun could be referring to the act of Callie styling her hair, which is an unwritten noun that the phrase creates.) Option B is incorrect because it uses an implied pronoun, not a vague pronoun. An implied pronoun is when there is no antecedent within the sentence to let us know what the pronoun is referring to. In this sentence, there are no people mentioned to let us know to whom “them” is referring to. Option C is incorrect because the pronoun has a clear antecedent. Both “Amelie and Jemma” and “clothes” are potential antecedents that the pronoun “they” could be accurately referring to according to pronoun-antecedent agreement rules. However, since we know that clothes cannot have a great time because they are inanimate objects, it is clear that the pronoun “they” must be referring to “Amelie and Jemma.” Option D is incorrect because there is a clear antecedent that the pronoun “it” must be referring to. This sentence may sound a bit confusing because there are three nouns listed in the subject: “tank,” “fish,” and “filter,” and the pronoun “it” could theoretically be referring to any one of them. However, upon basic examination, we can see that “it” cannot be referring to “fish,” because “fish” is being used here as a plural word (which can be understood from the fact that it does not say “a fish”), and the word “they” would have been used if it were referring to “fish.” Additionally, it does not follow logically that “it” would be referring to “filter,” because we are talking about a case in which there was no filter. When discussing a situation in which one has a tank “without a filter,” and one uses a pronoun to refer to something in this scenario, the pronoun must be referring to one of the nouns present in the scenario. Since we have established that there is no filter, the only singular noun present is “tank.” Therefore, this is not an example of vague pronoun use.

The correct answer is (A).

An idiom is a sentence or group of words that are part of the tradition of a language. Idioms are used to make language more expressive and colorful, and usually have a figurative rather than a literal meaning. For example, the idiom "to pull someone's leg" means to joke with someone.

Answer (A) is correct because "to wrap your head around [something]" is an idiom meaning to understand something.

Answer (B) is incorrect because it contains an expression that is a hyperbole (extreme exaggeration), but does not contain an idiom. While it does emphasize the point that people often do not get a sense of the scale of the universe by reading books, "you could read thousands of science books" is not an idiom.

Answer (C) is incorrect because it contains a metaphor that is not an idiom. "Provides a guided tour of the universe" is a metaphor because a film cannot actually take people on a tour, especially not of the whole universe!

Answer (D) is incorrect because "the viewer feels like both an ant and a giant" is a simile that is not also an idiom. In a simile, the words "like" or "as" are used to make a comparison.

The correct answer is (B).

The author uses second person a few times in the text as side notes after stating facts about fleas: "Imagine not eating for a hundred days!" "Imagine eating 1300 pounds of pasta in one day!" "That is the same as you jumping to the top of the Empire State Building." Using second person puts the reader in the same situation as the flea to help the reader grasp how remarkable the flea is. Therefore, the correct answer is (B). Answer (A) is incorrect because the passage does not discuss a topic that everyone is familiar with. Not everyone is familiar with trivia facts about fleas. Answer (C) is incorrect because the passage does not mention that fleas can live on human bodies to pull the reader into the text, but as part of the list of hosts fleas can live on. Answer (D) is incorrect because describing fleas does not pull the reader into the text.

Answer (B) is correct because the prefix bi- means "two."

Here is the word bidirectional used in a sentence: Central Boulevard is bidirectional: there are both eastbound and westbound traffic lanes. See the Study Guide for a list of prefixes to indicate numbers. Here are other words using the prefix bi- bi + lingua (language)= bilingual= knowing two languages bi + ped (foot) = biped = walking on two legs bi + cent (hundred)= bicentennial= two hundredth anniversary bi + weekly=biweekly=every two weeks bi + ocular (eye)=two eyes=binocular bi + partisan (side)=two sides=bipartisan (used to describe when opposing political parties work together)
