The correct verb pair to complete the sentence is:
C. comprenda, conozca
Explanation:
1. In this sentence, "No es cierto que la gente" is followed by a subordinate clause (subordinada) introduced by "que" which requires the use of the subjunctive mood (subjuntivo) in Spanish.
2. The subjunctive mood is used to express doubt, denial, uncertainty, or non-existence. In this case, the sentence expresses uncertainty regarding whether people understand (comprender) the history of the holiday and know (conocer) the culture of this country.
3. When we have a verb in the main clause that expresses doubt, denial, or uncertainty (like "No es cierto" in this case), and it is followed by a subordinate clause with a different subject, the verbs in the subordinate clause should be in the subjunctive mood.
4. Therefore, the correct verb forms in the subjunctive mood to match with "No es cierto que la gente" are "comprenda" (subjunctive form of "comprender") and "conozca" (subjunctive form of "conocer").
So, the correct verb pair is "comprenda, conozca" in this sentence.
