An “archive” is “a collection of historical documents or records.” So, because an archive is a collection of records, we need to pick out a noun that describes what constitutes a cookbook, or in other words, of what a cookbook is a collection. While “recipes,” “food,” and “ingredients” might each look like a potentially correct answer, “cookbook” is defined as “a book containing recipes,” so “recipes” is the correct answer.

A pallet is a thin, flat bed, usually filled with straw. A featherbed is filled with feathers, of which eiderdown is considered the best type for filling bedding. 

The relationship between "synonym" and "thesaurus" is that a thesaurus is a compilation of synonyms. We see a parallel relationship in the correct answer: a cookbook is a compilation of recipes.

A "tome" is a long and ponderous book. A library is the sort of place where one might find a "tome," where might one find a "tree"? The correct answer is an "arboretum" which means place where trees are grown. To provide further help, the Latin prefix arbor- means tree. Additionally, a "marina" is a harbor, a dockyard; an "estuary" is a mouth of a river, where the river meets the ocean; a "peninsula" is an area of land mostly surrounded by water; an "isthmus" is a narrow strip of land that connects two large landmasses, i.e. 'the Isthmus of Panama.'

A "reservoir" is a place where water is stored for future use. So, which of these is a place where food is stored for future use? The correct answer is a "granary." Additionally, an "auditorium" is the part of a theater reserved for the audience; a "sanctuary" is an asylum, a haven, a safe place; a "monastery" is a place where monks and other religious adherents live and practice their faith.

A "flagon" is a large container in which liquid is held and drunk from, typically something like beer or "wine." So, if a "flagon" holds "wine, what does a "perambulator" hold? Well, there is a clue in the word, the root -ambul- means walk, take steps. So, a "perambulator" is a "baby" carriage, a pram for short.

Since law is practiced in courts, we need to pick out an answer that describes a kind of building in which medicine is practiced. While "hospital," "doctor," and "medication" all have to do with medicine, only "hospital" refers to a building in which medicine is practiced, so "hospital" is the correct answer.

“Prognosticate” is a verb that means foretell. So, “prognosticate” is a verb that is associated with knowing information that has to do with the future, and we need to pick out an answer choice that is a verb that is associated with knowing information that has to do with the past. While “forget” and “remember” might each look like potentially correct answer choices, only “remember” has to do with obtaining information about the past, so “remember” is the correct answer.

A car is a mode of transportation that can travel via the highway. We see a parallel relationship in the correct answer: a boat is a mode of transportation that can travel via the ocean.

Since a shuttle takes off from a launch pad, we need to pick out an answer choice in which the first word is a noun indicating the location from which where the second word begins traveling. While "flame is to hot air balloon" might look like a good answer choice because hot air balloons can get nowhere without a flame, "dock is to boat" is the better answer because both launch pads and docks are locations, while a flame is not. Similarly, a flame is a component part of a hot air balloon that is present when the balloon is in motion, but launch pads are not part of shuttles after they are launched and boats do not bring their docks with them. Since boats embark from docks just like shuttles embark from launch pads, "dock is to boat" is the correct answer.
