Select the word that makes the following sentence grammatically correct.
Having ____________ one pill at bedtime, the patient was able to sleep for eight hours.
-
A
took
-

-
C
taking
-
D
taken
The word "taken" makes the sentence grammatically correct by providing the past participle required after the perfect participle "having."
A) took
"Took" is simple past tense—cannot follow "having" which requires a past participle to form the perfect participle construction. "Having took" violates verb form rules.
B) take
"Take" is base verb form—cannot follow "having" which requires past participle. "Having take" creates ungrammatical verb sequence lacking proper participle form.
C) taking
"Taking" is present participle—creates progressive perfect ("having been taking") when paired with "having," implying ongoing action rather than completed single event described by "one pill."
D) taken
"Taken" is past participle correctly completing the perfect participle "having taken." This construction expresses an action completed before another past action (sleeping), matching the temporal sequence required by the sentence context.
Conclusion
Perfect participles require "having + past participle" structure to express actions completed before other past events. "Having taken" provides the grammatically required past participle form, creating standard perfect participle construction showing pill consumption preceded sleep.
