  1. Question 1

    Q1. The water __________ by the purification system to make it safe for drinking.

    • A) is filtered
    • B) was filtered
    • C) has been filtered
    • D) will be filtered

    Answer: is filtered

    Explanation: 'is filtered' correctly uses the simple present tense in passive voice to describe a general or habitual action. 'was filtered' fails because it refers to a specific past action, not a general truth.
