10. Question 10

    Q10. A city's traffic congestion worsens during rush hour. What is a likely effect of this congestion?

    • A) Increased air pollution
    • B) Reduced travel time
    • C) Improved public transport
    • D) Decreased noise pollution

    Answer: Increased air pollution

    Explanation: Traffic congestion leads to increased air pollution due to idling vehicles. Reduced travel time is the opposite of what occurs.

11. Question 11

    Q11. A new species is discovered in a remote area. What could be a reason for its previously unknown status?

    • A) Recent evolution
    • B) Remote and inaccessible habitat
    • C) Extinction
    • D) Widespread distribution

    Answer: Remote and inaccessible habitat

    Explanation: Remote habitat makes discovery difficult. Recent evolution is unlikely for an established species.

12. Question 12

    Q12. A patient's symptoms worsen after stopping medication. What is a likely cause of this worsening?

    • A) Medication side effects
    • B) Disease progression
    • C) New illness

13. Question 13

    Q13. A river's water quality improves after pollution controls. What is a likely cause of this improvement?

    • A) Reduced industrial discharge
    • B) Increased agricultural runoff
    • C) More sewage dumping
    • D) Higher population density

    Answer: Reduced industrial discharge
