  1. A university states: 'No offer will be made to an applicant who fails to meet the minimum UCAT threshold.' Amir met the minimum UCAT threshold but did not receive an offer. Is this consistent with the university's statement?

    Answer: Yes, meeting the threshold is necessary but not sufficient for an offer

    'No offer without meeting the threshold' only makes meeting it a necessary condition, not a sufficient one; other criteria (interview, references) can still exclude Amir even though he cleared the threshold.

  2. In a class of 30 students, 18 study Biology and 15 study Chemistry, with 8 studying both. How many students study neither subject?

    Answer: 5

    Using inclusion-exclusion: students studying at least one = 18 + 15 - 8 = 25. Students studying neither = 30 - 25 = 5.

  3. A researcher observes: 'Every time the emergency department was overcrowded last month, ambulance handover delays also occurred.' Which conclusion is best supported?

    Answer: There is a correlation between overcrowding and handover delays, but causation is not established

    Repeated co-occurrence shows correlation, but the passage gives no experimental or mechanistic evidence establishing which (if either) causes the other, or whether both stem from a third factor.

  4. Five friends - Priya, Omar, Sam, Leila, and Tom - are ranked by exam score with no ties. Priya scored higher than Tom. Tom scored higher than Omar. Omar scored higher than Sam. Sam scored higher than Leila. What is the correct ranking from highest to lowest?

    Answer: Priya, Tom, Omar, Sam, Leila

    Chaining the four inequalities directly gives Priya > Tom > Omar > Sam > Leila, which matches option C exactly.

  5. A weather forecaster says there is a 30% chance of rain on Saturday and, independently, a 30% chance of rain on Sunday. What is the approximate probability that it rains on at least one of the two days?

    Answer: 51%

    P(at least one) = 1 - P(neither) = 1 - (0.7 x 0.7) = 1 - 0.49 = 0.51, or 51%.

  6. A clinic policy states: 'If a patient's temperature exceeds 38C, a nurse must be notified within 15 minutes.' A nurse was notified about a patient within 15 minutes. Which conclusion is valid?

    Answer: The patient's temperature may or may not have exceeded 38C

    The rule is a one-way conditional (temp > 38 implies notify within 15 min). Being notified within 15 minutes doesn't confirm the temperature exceeded 38C - the nurse could have been notified for another reason.
