The Full Sentence Analysis
"Through the 19th Century, the classics of Western Civilization were considered the (i) _______ of wisdom and culture, and an (ii) _______ person - by definition - knew them well."

Blank (i): The "Wisdom and Culture" Clue
The sentence sets up the classics as the source or container for "wisdom and culture." We need a word that means "a place where something is stored."
- A. repository: This word perfectly fits. A "repository" is a place where things are stored, kept, or can be found. In this context, the classics are the place where all wisdom and culture were kept.
- B. obituary: An "obituary" is a death notice. This makes no sense. The sentence is describing the classics as a living, valuable resource, not a notice of their death.
- C. frontispiece: A "frontispiece" is an illustration at the beginning of a book. While it relates to a book, it's too literal and small-scale. It doesn't convey the idea of being the ultimate "storehouse" of abstract concepts like wisdom.
- Winner: A. repository

Blank (ii): The "By Definition" Trigger
This is the most critical part of the sentence. The second half is creating a logical consequence of the first half. If the classics are the repository of wisdom and culture, then what kind of person is defined by knowing them well?
- D. educated: This is the perfect fit. If knowing the classics (the source of wisdom/culture) defines you, then you are, by definition, an educated person. This accurately reflects the 19th-century mindset, where a "classical education" was the gold standard.
- E. ecclesiastical: This word relates specifically to the Christian Church or clergy. While the classics are part of Western Civilization, a person isn't defined as being "churchrelated" just because they know them. This is too narrow. An educated person can be secular.
- F. obtuse: This word means slow to understand, or "thick." The sentence is creating a positive definition. Someone who knows the stored-up "wisdom and culture" of civilization well is, by definition, the opposite of obtuse (stupid). This choice is an antonym trap.
- Winner: D. educated

The "Logic Lab" Synthesis
The sentence sets up a powerful equivalence.
- (i) Classics $=$ The repository (storehouse) of all wisdom.
- (ii) Person who knows the classics $=$ The definition of an educated person.

This structure creates a perfect circle of logic. The correct answer is (A) for Blank (i) and (D) for Blank (ii).
