"Elude" is a verb that means "to escape from a danger, enemy, or pursuer, typically in a skillful or cunning way," so we need to pick out an answer choice that means something like "to escape in a cunning way." While all the answer choices may seem potentially correct because they all start with the letter "e," only "engross" and "evade" are verbs. "Engross" means "absorb all the attention or interest of," so it can't be the correct answer because it is not similar in meaning to "elude." "Evade," however, means "escape or avoid, esp. by cleverness or trickery," and since it is the answer choice closest in meaning to "elude," "evade" is the correct answer.

"Climb" could be substituted to maintain a similar meaning.

“Adhere” is a verb that means stick or stick to, so "stick" is the correct answer. As for the other answer choices, “propose” can mean suggest or share an idea or plan; “criticize” means point out the flaws in; “devour” means consume or eat completely; and “solemn” means sad and serious. For example, funerals are typically solemn occasions.

To "discharge" something means to eject it from something else, or to inform a person that he or she is able to leave, and sometimes that he or she must leave. That means that "eject," which means throw or toss out of, is the correct answer. None of the other answer choices are as close in meaning to "discharge" as is "eject": "fulfill" means achieve; "falter" means lose one's balance or composure; "arrange" means place in a specific visual organization, often one meant to be visually pleasing; "appoint" means assign a role to someone; and "consider" means think about carefully.

“Trespass” is a verb that means “enter the owner’s land or property without permission,” so we need to pick out an answer choice that means something like “enter an area without permission.” That means that “leave” cannot be the correct answer, because “leave,” when used as a verb, can mean “go away from,” making it an antonym, not a synonym, of “trespass.” “Encroach,” however, is a verb that can mean “intrude on (a person’s territory or a thing considered to be a right),” and because “encroach” is the answer choice closest in meaning to “trespass,” “encroach” is the correct answer.

To “tremble” means to shake, often with fear. To provide further help, “skirt,” when used as a verb, means go around or avoid; to “alert” means to tell someone about something; “perceive” means notice or look at; and “lessen” means make something less, usually to make something intense less intense.

To “prowl” means to walk around sneakily hunting or looking for something, so the correct answer is "slink" because "slink" means to move in a stealthy way. To provide further help, “nest” means the home of a bird or other nesting animal, or, when used as a verb, to make a nest; “sprint” means to run very quickly; and “host” means to welcome someone to an event, often in your home.

The word “conserve” means to save, to preserve, or to keep for later use. To provide further help, “average” means of middling quality; “progress” means move forward or towards a goal and “regress” means move backwards or further away from completing a goal.

"Illuminate" means to supply or brighten with light. Thus, "brighten," which means lighten or light up, is the correct answer.

"Sever" means disconnect or chop something off from something else. "Detach" means unfasten or separate, so it is the answer choice closest in meaning to "sever."
