"Famished" means extremely hungry, as does "ravenous," so "ravenous" is the correct answer.

Since "nutritious" is defined as nourishing or effective as food, "nourishing" is the best answer choice. "Unhealthy" and "nutritious" are antonyms.

"Conspicuous" means standing out so as to be clearly visible. "Noticeable," which means able to be easily noticed, is the best synonym of "conspicuous," so "noticeable" is the correct answer.

Incorrect answers:

"Invisible" means not able to be seen. It is an antonym of "conspicuous," which means clearly visible, so it is incorrect.

"Ordinary" means having no special or unusual features or normal, as in the sentence, "My house looks ordinary and doesn't stand out among the other houses in my neighborhood."

"Terrifying" means causing a feeling of extreme fear, as in the sentence, "I have a fear of heights, so while I thought that the Grand Canyon was beautiful from a distance, I found it terrifying when I stood at the edge and looked down."

"Murky" is an adjective that means very dark or foggy or not completely understood; so, we need to pick out an answer choice that means something like foggy or not understood. "Gloomy" means dark and depressing, so "gloomy" is the answer choice closest in meaning to "murky" and the correct answer.

Don't get this word confused with "horse," the animal! "Hoarse" means raspy or rough-sounding, especially when describing someone's voice. You've probably had a hoarse voice after getting a sore throat. "Smooth" means even or free of bumps; "artistic" means talented at art or creative activities, and "mountainous" refers to areas of land and means containing mountains.

"Frigid" means very chilly or cold. Therefore, the best synonym for "frigid" is "cold." While "snow" is cold, it is a noun, and does not mean the same thing as "frigid." "Different," "straight," and "solid" are each unrelated to the word "frigid." Therefore, "cold" is the best answer.

Have you ever been in a friend's house that seems almost too clean? Or walked by a lawn that was perfectly manicured? In situations like these, you could use the adjective "pristine," which means perfectly clean or untouched. The best choice for a synonym is clearly "spotless," which could also describe an impeccably clean environment. Both "dirty" and "marred" are antonyms, and "self-assured" simply describes a confident or assertive person.

The word "vivid" means very bright or lively. "Bright" is the best choice because it is a part of the definition of "vivid." Considering the other choices, "new" is unrelated in meaning to "vivid," "sight" is a noun that means the ability to see, and "cloudy" means foggy or unclear.

Something that is “delicate” is easily broken and fragile. To provide further help, “sturdy" means not easily broken or tipped over, “comforting” means providing comfort and making you feel better, "agile" means quick-moving and athletic, and "risky" means involving risk-taking and therefore dangerous and uncertain.

Something that is “hideous” is ugly, gross, and unpleasant. To provide further help, “generous” means giving of gifts and money; “beautiful” means very attractive and good-looking; “intriguing” means interesting and fascinating; and “effortless” means requiring or seeming to require no work or effort.
