Sharpening an Essay's Focus and Illustrating a Given Statement (TOD 504)

These questions ask you to pick the sentence that does a specific job: either narrow a vague subject down to the essay's real topic, or give an abstract claim a concrete example a reader can picture. Both moves fight the same enemy: vagueness. 'Many animals cross the dune field' could be about anything with legs. 'Three species of desert fox cross the dune field' tells you exactly what the essay is tracking. That's sharpening: trading a broad, generic noun for the specific one the paragraph is actually built around.

Illustrating works differently. A claim like 'the repairs were expensive' is a judgment, and a judgment needs a case the reader can measure. 'Regilding one horse alone came to the full budgeted amount, and the carousel carries thirty-six horses' gives you a number to feel the cost through. A sentence that's merely vivid but describes something else entirely doesn't count, even if it's well written, because illustrating means giving evidence for THAT claim, not just adding color to the paragraph. Check what the sentence is proof of before you check how good it sounds.

When the statement being illustrated is a number instead of a judgment, the job shifts from proving to translating. 'The seed vault holds thousands of wheat varieties' is already a fact; a reader just can't feel its size. So the next sentence converts the number into something human-scaled, like a farmer who'd need more than a lifetime to plant them all one variety a day. Sharpening and illustrating both sit inside the bigger skill of matching a sentence to the exact job the question names, rather than just picking whichever option sounds nicest.
