"Limber" is an adjective that means "flexible" or "bending easily," so we need to pick out another adjective that also means "flexible." While "stretched" may look like a good answer because "flexible" means "able to stretch," "stretched" does not mean "flexible," so it can't be correct. "Lithe," on the other hand, means "characterized by flexibility and grace," and since it is closest in meaning to "limber," it is the correct answer.

“Grubby” is an adjective that means either “dirty; grimy” or “disreputable; sordid.” So, we need to pick out an answer choice that means something like “grimy” or “disreputable.” That means that “spotless” cannot be the correct answer, because “spotless” is an adjective that means “absolutely clean or pure; immaculate,” making it an antonym, not a synonym, of “grubby.” “Filthy,” however, is an adjective that can mean “disgustingly dirty,” and because “filthy” is the answer choice closest in meaning to “grubby,” “filthy” is the correct answer.

"Arid" means dry; Moist means slightly wet; Inundated means flooded; Desert is a place that has sand and is dry; and Outer space it the area outside the earth's atmosphere.

"Torrid" means scorching hot or extremely challenging. In this instance the best synonym for one of those meanings is “stifling” which means uncomfortably hot. For clarification, a dispute is an argument or disagreement; mediocre describes something that is average in a negative way; whimsical means silly and quirky; frigid means very cold, and is an antonym of stifling and torrid.

Something that is "immaculate" is perfect, clean, unblemished or spotless. The other four answer choices are all antonyms of immaculate.

"Fragile" means breakable.

"Luscious" means delicious.

"Industrial" means of or relating to manufacturing or heavy-duty. None of the other answers are close in meaning to "industrial": "prolonged" means extended; "eventful" means significant; "rural" means of or relating to the countryside, as opposed to the city; and "current" means of, related to, or happening at the present time.

"Dingy" means grimy, dirty or depressing, so "grimy" is the correct answer.. For clarification, "immaculate" means perfect, unblemished, or spotless, and is an antonym "dingy" and "grimy." As for the other answers, "careless" means inattentive; "careful" means cautious or attentive, and "pointless" means futile.

"Gaunt" means very skinny or skeletal and is most similar in meaning to "emaciated," which means skinny to the point of ill health. So, "emaciated" is the correct answer. "Corpulent," "portly," and "rotund" all mean fat or round and are antonyms of "gaunt" and "emaciated," and "fraudulent" means fake or false.
