When someone is neglectful, they do not care or provide care where it is needed. The analogy could be expressed as a lack: “As something neglectful lacks care, so does something adulterated lack X.” Although we use the term “adultery” to describe someone who has committed an act against marriage, the word “adulterate” comes from the Latin meaning to corrupt, in the sense of to ruin the purity of. We could adulterate a sample of water by adding foreign elements (and so forth). Thus, something that is adulterated lacks its appropriate purity.

The word “credence” means belief in the truth of something. If someone is "trustworthy," we are likely to give credence to his or her words or claims. Something "malicious" is evil or ill-intentioned and harmful. Such a thing or person deserves to be feared, which adequately fulfills the parallel for this analogy.

The word “immaculate” comes from the combination of the “i-” prefix used as a privation (i.e. not) to the root which means stained, spotted, or dirty. Thus, the word means not stained, and generally is used to mean completely clean. Thus, the analogy could be rewritten, “Just as something immaculate lacks any dirt, so does something innocent have no X.” An innocent person lacks guilt, which is the best answer among those provided.

If you regard things with credulity, you find nothing unbelievable. If you regard things with apathy, you find nothing interesting.

The word “pulmonary” comes from the Latin word for the lungs. It is used to in English to describe physical conditions related to these organs, as when someone has pulmonary embolism, which is a type of blockage of blood to the lung. Just as “pulmonary” describes the lungs, “cardiac” describes conditions related to the heart.

To be craven is to lack bravery. To be scarce is to lack abundance.

A recluse is someone who is defined as being solitary or apart from society. An artist is someone who is defined as being creative. Thus, the two relationships between the pairs of words are the same.  

The word "nomadic" can be a characteristic of a tribe. Therefore, the correct answer will be an answer choice that can be described as "permanent." The word "permanent" is used as the opposite of "nomadic," so in this context it means non-moving or consistently located in the same location. The noun that is best described by this word is "city," which is therefore the correct answer. 

Torrid describes the weather in the tropics, and frigid describes the weather in the arctic. 

A glutton is someone who is greedy and selfish; restraint means ability to control oneself and prevent oneself from over-indulgence. A glutton is someone who would not show restraint so to solve this analogy you must identify what kind of behavior a braggart would be unlikely to demonstrate. A braggart is someone who boasts and is arrogant (think “brag”) so you can determine that a braggart would not demonstrate “modesty.”
