A words in context question tests whether you can use the text to find what a missing word must mean. Read the whole text to find the clue, then ask whether the blank agrees with it, turns against it, or gives a cause or result. A word such as without adds a reversal: the blank names what the sentence rules out, not what happens. Predict in plain words, then check each choice's exact meaning rather than its sound or general tone.
Hints
- Hint 1
Compare what someone sees normally with what ultraviolet light reveals in the first sentence.
- Hint 2
What does the last phrase tell you about why the difference between original paint and later repairs matters?
- Hint 3
The blank follows without. Use the clue to work out what happens, then flip that meaning to name what is avoided.
Step-by-step
Find the clue, then flip the meaning
Step 1Read the contrast
The repair can match the surrounding colors at ordinary viewing distance yet remain distinguishable under ultraviolet light. What does that contrast tell us about the repair? It can make the mural look whole while still allowing someone to tell original paint from the repair. The sentence with the blank has to explain how the repair can do both: blend in while still being possible to tell apart.
- Step 2
Flip for without
The word without tells us the repair avoids doing whatever fills the blank. How do we turn our clue into a word for that slot? Old and new paint can still be told apart, so the repair is not wiping out the distinction between original paint and later intervention. That's the flip we need: the sentence says the difference survives, but the missing word names its loss. Predict erasing the distinction.
- Step 3
Test the choices' meanings
Which choice names what the repair avoids doing in without ______ the distinction? Perpetuating means keeping something going, so without perpetuating would say the repair doesn't preserve the distinction. Exaggerating means overstating, while recasting means changing how something is presented or understood. Overstating or rethinking a difference isn't erasing it, which is what our prediction calls for.
- Step 4
Check the word against future study
Effacing means erasing or wiping out. Why does without effacing fit a distinction crucial to future study? Future researchers need to tell original paint from repairs, so the difference can't be erased. The phrase describes keeping that difference from being erased, which is exactly what the special materials allow. Choice A.
