Answer key: B1 Preliminary · Part 1: Multiple Choice · Swimming pool, train delay and jam label

For the teacher. Each answer comes with the reason it is right.

1. B: It will only be open early in the day and in the evening.
The fast lane is open ‘only before 9 a.m. and after 7 p.m.’, so B is correct. A is wrong because between those times the lanes are for general swimming, not closed for children. C reverses the times: 9 a.m. is when the fast lane stops, not when it opens.
2. A: watch the start of the film and leave Lukas’s ticket at the desk
Lukas writes ‘Go in without me and leave my ticket at the desk’, so A is correct. B is wrong because he tells Kofi not to wait. C is wrong because Lukas only says he will miss the start; he does not ask to change the tickets.
3. C: Once open, it keeps for about a month in the fridge.
The label says ‘Once opened, store in the fridge and eat within four weeks’, so C is correct. A is wrong because before opening it only needs a cool, dry place. B is wrong because the four weeks start when the jar is opened, not on the date it was made.
4. A: to say her bike is ready and costs less than expected
The bike is ‘ready to collect’ and the total is £24, ‘not the £40 we expected’, so A is correct. B is wrong because the brakes were checked and did not need work. C is wrong because Saturday is only mentioned for the closing time.
5. C: keep their leftover food separate from their plates
Students must put uneaten food ‘in the green bins, not on your plate’, so C is correct. A is wrong because only plates go on the top shelf. B is wrong because trays go on the racks, not in the green bins.
