Extract:
Select the word that will make the following sentence grammatically correct.
The lounge needs a thorough cleaning, ____________ the windows must be washed.
-
A
or
-
B
and
-
C
but
-
D
yet
The word "and" makes the sentence grammatically correct by connecting two related actions that complement each other rather than contrasting.
A) or
"Or" presents alternatives—suggesting either cleaning OR washing windows, not both. Context implies both actions are needed for thorough preparation.
B) and
"And" correctly connects two related, complementary actions forming a compound predicate. Both cleaning the lounge and washing windows contribute to overall tidiness—logical additive relationship requiring coordinating conjunction "and."
C) but
"But" introduces contrast or exception—semantically inappropriate when both actions support the same goal without opposition. No contradiction exists between cleaning and washing.
D) yet
"Yet" introduces unexpected contrast—similar to "but" but with stronger surprise implication. No unexpected element exists between these logically connected cleaning tasks.
Conclusion
Coordinating conjunctions must match the logical relationship between clauses. Complementary actions contributing to a unified goal require additive "and"—not alternatives ("or") or contrasts ("but," "yet") that imply opposition or exclusivity where none exists.
