"Transcend" is a verb that means "be or go beyond the range or limits of something abstract, typically a conceptual field or division," or "surpass a person or an achievement." So, while "concerned with" or "beleaguer" might each look like a potentially correct answer because each answer choice can concern abstract details, "go beyond" is the answer choice closest in meaning to "transcend," so it is the correct answer.

"Aggrandize" and "augment" both mean to increase or enlarge. "Abridge" means to shorten or curtail. "Debilitate" means to incapacitate or cripple. "Expedite" means to accelerate. "Jettison" means to eject or throw overboard. 

Germinate means to grow or sprout. "Relish" means to enjoy or take delight in doing something. "Quell" means to subdue or put down. "Reinforce" means to support or strengthen. "Renounce" means to abandon or reject.

The word “taint” comes distantly from the Latin word for “to dye” and is likewise related to the English “tinge,” meaning, “to give a slight coloration to something.” The general idea expressed by “taint” is that something is being polluted or contaminated by another thing. One could say, “The water was tainted with fish blood, making it impossible to drink.” Likewise, one could use the term in a metaphoric sense like, “Ronald’s negative attitude tainted the positive spirits of the entire group, reducing everyone’s enjoyment.”  When something is “adulterated,” it is corrupted, generally by adding something of worse quality to something of better quality.

The word “vacate” is related to vacuum, as it comes from the Latin for “to leave empty.” When someone vacates an area, he or she leaves it. For instance, you likely have heard the expression “vacate the premises.” This expression means, “to leave the building or property.” The word is distantly related to “vacation,” which can merely mean “to be unoccupied,” as though you had “empty time on your hands.”

"Occlude" and "impede" both mean to hinder or block a process. "Facilitate" means to assist the progress of. "Enervate" means to tire or wear out. "Castigate" means to criticize severely. "Assuage" means to soothe or relieve. 

"Oscillate" means to fluctuate or change back and forth; think of an oscillating fan. "Levitate" means to rise into the air. "Abdicate" means to give up a right, position, or power. "Bungle" means to blunder or mess up. "Refuse" means to deny or say no.

The word “truncate” comes from Latin roots for “to maim” (to wound by causing a body part to become useless). This word is generally applied metaphorically to mean “to cut short.” For instance, one can say, “The message was truncated unexpectedly, sending only the first half of the contents.”

We might often think of “conjuring” in terms of magical tricks. The word actually can mean “to bring to mind,” as in, “The smell of pumpkin pie conjures images of Thanksgiving Day dinner for many American adults.” Likewise, it can have the more general meaning of “to produce unexpectedly,” as in, “I was always amazed that my mother could conjure up the most beautiful Christmas decorations in spite of our dire poverty.” For this reason, “produce” is the best option among those provided.

"Enervate" is a verb that means "cause (someone) to feel drained of energy or vitality; weaken." So, we need to pick out an answer choice that means something like "weaken." "Fortify" cannot be the correct answer, then, because "fortify" can mean "strengthen or invigorate (someone) mentally or physically," making it an antonym, not a synonym, of "enervate." "Enfeeble," however, is a verb that means "make weak or feeble," and because "enfeeble" is the answer choice closest in meaning to "enervate," "enfeeble" is the correct answer.
