Sentence Structure

• [BLANK - varies across choices, completing the main clause]

Understanding the Meaning

Let's start reading from the beginning:

'Constructed with traditional techniques passed down through generations—that is, methods refined over centuries of craft practice—'

This opening phrase is telling us about something that was built:

• It was constructed (built) using traditional techniques
• These techniques were passed down through generations
• The phrase clarifies: these are methods refined over centuries

Now here's where we need to fill in the blank. This opening phrase is describing something that was constructed with these traditional methods.

Let's look at our choices to see what could follow:

• Choice A: medieval stonemasons created cathedrals...
• Choice B: the testament to exceptional craftsmanship is visible...
• Choice C: cathedrals from the medieval period still stand...
• Choice D: exceptional craftsmanship is testified to...

What do we notice here?

The opening phrase "Constructed with traditional techniques..." is a modifier—it's describing something. Whatever noun comes immediately after this phrase must be the thing that was constructed.

Let's check what makes logical sense:

• Were stonemasons constructed? No, they did the constructing.
• Was a testament constructed? No, a testament is evidence or proof, not something physically built.
• Were cathedrals constructed? YES—cathedrals are buildings that were constructed.
• Was craftsmanship constructed? No, craftsmanship is a skill or quality, not something physically built.

So we need Choice C: "cathedrals from the medieval period still stand as testaments to exceptional craftsmanship."

This makes perfect logical sense: The cathedrals were what was constructed with those traditional techniques, and they still stand today as evidence of exceptional skill.

GRAMMAR CONCEPT APPLIED

Introductory Modifying Phrases Must Describe What Immediately Follows

When a sentence begins with a descriptive phrase (called a participial phrase in grammar terms), that phrase modifies—or describes—the subject that comes right after it. The noun that follows must logically be what the phrase is describing.

Pattern:

• Introductory modifier: Baked fresh this morning,
• Subject (what was baked): the bread smelled wonderful.
• ✓ Correct: The bread was baked fresh this morning.

• Introductory modifier: Baked fresh this morning,
• Wrong subject: the baker sold all the bread.
• ✗ Incorrect: This suggests the baker was baked, which is illogical.

In this question:

• Modifier: "Constructed with traditional techniques passed down through generations"
• What was constructed? Cathedrals (Choice C)
• ✓ Correct: Cathedrals can be constructed.

Wrong subjects in other choices:

• Stonemasons (A) - people aren't constructed
• Testament (B) - evidence isn't constructed
• Craftsmanship (D) - a quality isn't constructed

The key is to ask yourself: What does this opening phrase logically describe? Whatever that is must be the subject that comes right after the comma or dash.
