What examiners said
Few candidates recalled the use of fuel oil as the fuel for ships or home heating systems. The most common answer was fuel for cars.
— Examiner report, May/June 2025, 0971/31 Q4(a)(ii) (Cambridge)
Many candidates gave vague answers to this question. Common answers were ‘for medicine’, ‘for making bread’ or ‘for alcoholic drinks’. Candidates should note that ethanol is not manufactured separately and then added to other liquids to make alcoholic drinks. Pure ethanol is a poison and so ‘use as a beverage’ is not a marking point on this paper.
— Examiner report, May/June 2025, 0971/31 Q4(d)(ii) (Cambridge)
This was answered extremely well. Methane was seen occasionally.
