As the play is four hours long we can infer that after a couple of hours the play would be half-way over. At the halfway point of most long plays there is a break, also known as an “intermission.” The prefixes inter- and intra- are similar to one another, but have one key difference. Inter- means between and intra- means within. “International” means global, between the countries of the world; “intramural” means within an organization. Additionally, “infrastructure” is buildings and transport facilities that keep a community moving forward; “intravenous” means needed to be injected into. 

It is likely the subject of the sentence would go see a doctor who specializes in sleep therapy. The prefix hypno­- means related to sleeping, so the correct answer for the first black is hypnotherapist. Alternatively, you could determine the correct answer based on the information about the doctor. An “untrained” doctor probably has qualifications that are likely not to be real, or to be phony.

To provide further help, a “pediatrician” is a doctor who specializes in childcare; a “somnambulist” is someone who sleep-walks; “authentic” means genuine, real; an “orthodontist” is someone who specializes in the medical care of teeth; “implacable” means unstoppable, relentless. 

If people are astonished when the subject of this sentence is finally defeated, he had most likely been considered unbeatable, or invincible.

“Adversary” is another name for enemy or opponent, so it is the most appropriate fit for the second blank.

To provide further help, “implacable” means relentless; “ally” means partner, friend; “vicarious” means sensational; “nemesis” is an enemy; “vacuous” means vain, empty-headed; “co-conspirator” is someone who helps plan and execute a conspiracy; “uniform” means standard; “volition” means will, desire. 

Note that "nemesis" is also an appropriate choice for the second blank, but "vicarious" makes no sense in the first blank, so we can eliminate that answer choice.

As the student always gets poor grades in math, it stands to reason that his or her “arithmetic” would be rudimentary. “Rudimentary” means not well developed, basic. It also stands to reason that a teacher would advise a student that he or she can do or succeed in anything if the student keeps working at it; this should lead to an answer choice of accomplish.

To provide further help, “theology” is the study of religion; “undermine” means weaken; “hesitate” means delay, wait for something; “geometry” is a type of mathematics concerned with shapes; a “conglomerate” is a large, combined, business; “gratuity” is a tip given to someone who provides good service; “affix” means stick to. 

To finish this sentence you have to know that executing criminals can also be referred to as capital punishment. Many people might have selected “corporal” (which means of the body) punishment, but this does not capture the real meaning of the sentence.

To provide further help, “recreational” means done for the purposes of fun or enjoyment; “credulous” means disbelieving; “rakish” means charming, casual.

As the author of this subject did not wish to be recognized it makes sense that he would go to the party in a disguise, or incognito. The word fragment cogn- refers to knowledge or identity.

To provide further help, “unaccompanied” means alone; “condensed” means thick, reduced together; “afflicted” means suffering with; “forlorn” means sad and feeling hopeless. 

The context of the sentence suggests that we are looking for an answer choice that refers to the condition of buildings, so the correct answer is “infrastructure.” "Setting" is a decent answer choice, but since "infrastructure" specifically refers to buildings and the sentence specifically discusses the state of buildings in the area, "infrastructure" is the best answer. "Hotels" and "mansions" are too specific to be the correct answer since the sentence refers specifically to "buildings," a more general word.

Since Donald has "written many books about Greece," we can infer that he knows a lot about that topic. So, we need to pick out an answer choice that means something like knowledgeable. The word that best fits the sentence's blank is "erudite," which means learned and scholarly. As for the other answer choices, "absent" means not present or missing, "enigmatic" means mysterious, "expansive" means extensive or communicative, and "exultant" means triumphant or delighted.

From the context of the sentence, you know that the blank word must describe the king’s lack of mercy and compassion. The correct answer is therefore “ruthless," which means showing no mercy or violent. To help you, "benevolent" means good-natured, "supple" means flexible, "intelligent" means smart, and "gregarious" means sociable.
