A "banquet" is a formal dinner party for many people, so the answer choice closest in meaning to "banquet" is "feast," which when used as a noun, means a meal with a very large amount of food. None of the other answers are close in meaning to "banquet": "jubilation" means happiness; "obsolete" means old and outdated; a "challenge" is a difficult task; and "antiquity" means ancient times, or often specifically the Classical era.

"Border" is defined as the line at which two geographical areas like states or countries meet, so "boundary," which means the edge of something, is our best choice, because "border" and "boundary" can both mean the edge of an area.

A "barrier" is something that gets in the way, an obstacle, or a barricade blocking the way, so "obstacle" is the correct answer.

A "carnivore" is an organism that eats only meat, so "meat-eater" is the correct answer. An "herbivore" is an organism that eats only plants, and an "omnivore" is an organism that eats both meat and plants.

Since "infection" is defined as an affliction with a disease-causing organism, "disease" is the best answer choice.

A "company" is a business, so "business" is the correct answer. A "president" is in charge of a company; a "factory" manufactures items; an "employee" works at a company; and an "inventor" creates something new.

As for the other answer choices, a "country" is a nation; "paper" is flat sheets made out of wood pulp that are written on; the "capital" is the major city of a state or country in which the government is headquartered; and "vacation" means a break or time off from work or school.

"Ache" and "soreness" both relate to dull pain that one can feel. 

“Parcel” is a noun that can mean “a thing or collection of things wrapped in paper in order to be carried or sent by mail,” so we need to pick out an answer choice that means something like “a thing wrapped in paper to be sent by mail.” That means that “paper” cannot be the correct answer, because if a “parcel” is by definition wrapped in paper, it is probably not paper itself. “Package,” however, is a word that when used as a noun, can mean “an object or group of objects wrapped in paper or plastic, or packed in a box,” and because “package” is the answer choice closest in meaning to “parcel,” “package” is the correct answer.

"Coating" can refer to a thin layer of a particular material, so "layer" is the correct answer. For instance, one might write, "After one coating of paint, you could still see the grain in the wood of the dresser, but after the second coating of paint, it was completely covered up."
