“Origami” is defined as the Japanese art of paper folding, so a piece of origami would be made out of paper. That means that we need to pick out an answer choice that describes the material out of which a tapestry is made. While “cloth,” “clay,” and “metal” might each look like a potentially correct answer, “tapestry” is defined as a thick piece of cloth with intricate illustrations woven into its design. Because a tapestry is made of cloth just as a piece of origami is made of paper, “tapestry” is the correct answer.

A bookshelf might be made of wood, so to solve this analogy, you need to pick out an answer choice that is a material that a window might be made of. The only answer choice that makes sense in this capacity is "glass," since windows are made of glass.

"Caffeine" is found in abundance in "coffee," it is what causes "coffee" to give you energy. So, to solve this analogy you need to determine which of these is found in "cigarettes."

There are many "carcinogens" in "cigarettes" and some too in "coffee."

A "glacier" is a slow moving large object comprised of "ice." To solve this analogy you therefore need to determine what it is that "comprises" (makes up, constitutes) an "orchestra."

A "lagoon" is a pool of "water." A "lagoon" is made of "water," so to solve this analogy you need to determine which of these is made of "grass." The correct answer is "knoll." A "knoll" is a small, grassy hill.
