Explanation:

To solve this word - study problem, we analyze each base word and determine its different word - form (noun, adjective, adverb) by using common prefixes, suffixes, and dictionary - based knowledge of word derivations.

For the base word "space"

• Adjective form: To form an adjective from "space", we can use the suffix "-ious". The adjective form is "spacious", which means having a lot of space.

For the base word "rude"

• Noun form: By adding the suffix "-ness" to "rude", we get the noun "rudeness", which refers to the quality of being rude.
• Adverb form: We add the suffix "-ly" to the adjective "rude" to form the adverb "rudely", which describes how an action is done in a rude manner.

For the base word "silence"

• Adjective form: By adding the suffix "-t" (a common way to form an adjective from a noun ending in "ce"), we get "silent", which means without sound.

For the base word "obscure"

• Noun form: We add the suffix "-ity" to "obscure" to form the noun "obscurity", which refers to the state of being obscure (not well - known or difficult to understand).
• Adverb form: We add the suffix "-ly" to the adjective "obscure" to form the adverb "obscurely", which describes how an action is done in an obscure way.
