This analogy is relatively simple, all you have to note is that “cold” describes ice. Thus, you are looking for something that describes the sun. All of the incorrect options are related to the “location” of the sun (i.e. “in” the sky) or when it is in the sky (“morning,” “daytime,” “diurnal”). None of these pertain to a description of the sun itself. Though simple, the best option is “bright.”

To "abhor" something is to loathe, despise or hate it. You might "abhor" violence and refuse to watch TV shows that promote violence. "Covet" and "desire" both mean to want something, so these are antonyms of abhor. "Instigate" means to start something and "enhance" means to make better.

"Lucky" and "fortuitous" mean roughly the same thing, just as "drab" is another word for "dreary."

In days past, a portrait would be painted by a painter. It was the thing created by the painter; therefore, this analogy is one of “maker to thing made,” as though to say, “As the painter makes a portrait, so a composer makes X.” Among the options provided, only “symphony” describes what a composer would make. He would write the musical score for the symphony, which can just be called “a symphony” indicating the musical score itself.

Something is gory when it is covered with blood, often shed because of violence. Thus, “bloody” is either a synonym or at least a characteristic of something that is “gory.” When something is “saturated,” it is completely filled. This word is most frequently used to mean “completely filled with water,” like a sponge that is fully saturated. The word is used in scientific expressions like “saturated fats” because these compounds are completely full of a particular kind of bond—they are saturated with them.

"Forlorn" means miserable or sad. "Ecstatic" is the antonym; it means extremely happy. "Arrogant" means conceited or full of oneself. "Informed" means having knowledge or information regarding a topic. "Significant" means important or noteworthy.

"Advance" is the opposite of "retreat," so therefore the opposite of "ascend" would be "descend," or to go down.

When water cools, it becomes ice; therefore, this analogy requires that which magma becomes when it cools. Magma is the liquid stone that flows under the earth’s crust. When this cools, it becomes stone again. This is the only option that fits among those provided.

A "balcony" has a "railing" to keep people safe, much like a "road" has a "guardrail" to keep cars and their drivers safe.
