A person who is generous is likely to give a donation to some cause. Thus, the analogy could be read as, “As a generous person is likely to give a donation, so something that is ancillary is likely to provide or give X.” The word “ancillary” comes from the Latin “ancilla,” meaning female servant. In English, something "ancillary" is something that provides secondary support or aid to an operation or undertaking. Thus, among the options provided, “aid” is the best.

“Tactile” is an adjective that means “dealing with the sense of touch” or “perceptible by touch.” So, something that is perceptible via the sense of touch is tactile, and we need to pick out an answer choice that describes with what sense something “olfactory” is perceptible. While all of the potential answer choices except for “idea” are connected with specific senses, “olfactory” is an adjective that means “relating to the sense of smell,” so “smell” is the correct answer.

You need a ticket to engage in the lottery, and a ballot to make a vote. The second item is the piece of paper that lets you take part in the activity.

When we use a telephone, we communicate using our voice. Similarly, when we write a letter, we communicate using our writing.

Yellow is the color of signs that mean caution, and red is the color of signs that mean stop. 

This is a word game analogy. The second word in each pair is an anagram of the first. Spa anagrams to asp and stink anagrams to knits.

"Flora" and "fauna" are the scientific names for plants and animals, respectively. So, "flora" are plants and "fauna" are animals. This is the only information you need to solve this analogy.

To begin with "corroborate" means offer evidence in support of a claim made by another person and "testimony" is a formal statement given about how something happened. One can "corroborate" a story, so to solve this analogy you need to determine which of these is an action that one can do to "testimony." The correct answer is "verify" which means prove as true, prove to be valid. In the context of this sentence "corroborate" and "verify" are also synonyms of one another. Additionally, "denigrate" means criticize harshly, make fun of unfairly; "atrophy" means weaken due to lack of use; "amplify" means make louder, make more intense; "vilify" means portray as a villain, demonize. 

"Cartography" is the science of map-making, the art of making maps. So, to solve this analogy you need to determine which of these answer choices "seismology" is concerned with. The correct answer is "earthquakes."

An "invoice" is a bill. "Delinquent" means not paid at the desired or directed time. So an invoice that is late is "delinquent." (There is another definition of "delinquent," a person who frequently does illegal or immoral things.)

A "check" that is late is not called "void." (To "void" a check means to render it unpayable, so there is a sort of connection between "check" and "void," but not the best connection out of all the answer choices.)

Is a late account opened? No, that makes no sense. An "account" (as in a checking account) is "opened" (created), but that has nothing to do with being late.

Is a "book" that is late overdue? Yes. If you check out a book from a library and do not turn it in by its due date, it is termed overdue. So "book is to overdue" is the answer.
