If someone is nonchalant about a test grade, it means he or she is unconcerned or aloof.  Nonchalant is defined as laid back or not easily excited.

Two of the wrong options attempt to have you confuse "elated" with "related." (These wrong options are "connected" and "associated".) To be "elated", however, is to be very happy. The word "ecstatic" means just this as well. It actually comes from root words meaning standing outside. Have you ever heard someone say, "She was beside herself with joy!" This means the person was almost "outside" herself because of her strong feelings. To be "ecstatic" is to be very happy in this way.

When someone is "affectionate," he or she is very caring and loving toward other people. Now, while such a person might also tend to be helpful, joyful, or even bubbly, these meanings are not strict synonyms for "affectionate." Affection is, above all else, about love. Thus, the best synonym among those provided for "affectionate" is "caring." (The word "caring" means more than "helpful"—it indicates an emotional attachment. This makes it a better option.)

The word "glee" means a great amount of happiness. Thus, a gleeful person is very happy. We could say, "The baby was utterly gleeful while playing with the small dog, giggling and slapping playfully at the ground." The main thing that you want to express with the word "gleeful" is happiness.  (Often, this happiness comes with great energy too; however, gleefulness is about happiness.)  Thus, the best option is "joyful."

The word "depressed" is used to describe someone who is very unhappy. When a person is "miserable," he or she is not happy or is very negative about life. Among the options given, this is the only one that closely matches "depressed".

"Furious" is an adjective meaning extremely angry. The only answer choice with a similar meaning is "enraged," which means very angry. The other words do not have similar meanings: "gruff" can mean no-nonsense or abrupt; "superb" means excellent; and "annoyed" means only slightly angry.

When someone behaves "erratically" they are acting in a way that is not expected, usual, nor even predictable. Therefore, "unpredictable" would be the word closest to this meaning and is a synonym for erratic.

A “visionary” is someone who has the vision to see creative solutions to problems, a creative thinker. To provide further help, “uncontrollable” means not able to be controlled; “potent” means powerful; a “portent” is an omen.

"Kin" is a noun that means "one's family and relations," or an adjective that means "related." So, we need to pick out an answer choice that means something like "one's family." While "connected" may look like the correct answer, because people who are "kin" are connected to each other, "connected" does not mean the same thing as "kin," so "connected" cannot be the correct answer. "Relative," however, can not only function as an adjective that means "considered in relation or in proportion to something else," but also as a noun that means "a person connected by blood or marriage." So, because "relative" is the closest synonym to "kin" amongst the listed answer choices, "relative" is the correct answer.

A foe is the opposite of a comrade and is defined as an enemy.
