The Number That Changes After 'But'
Mika, a third-year student, is practising the listening section, where each recording is played twice. The script she hears is:
'Boys and girls, the science club meets at 4:30 on Friday as usual. But this Friday we will start at 4:45, because Mr Sato has a meeting until 4:30. We will meet in Room 2, not Room 1.'
The question asks what time the science club starts on Friday. Mika writes 4:30. On a second item - 'The library closes at 6:00, but during test week it closes at 5:30' - she writes 6:00. Asked to explain, she says: 'I heard 4:30 first, and 4:30 is the club's time, so I wrote it. I can't write and listen at the same time, so I write the first number I catch.' She also leaves answers blank whenever she misses the opening line of a dialogue.
1. Name the trap this item is built on and explain why Mika's 4:30 is a decision error rather than a hearing error. Then give the note-taking routine she should use for every number item.

What the item is built to test. Not the number itself, but whether the listener lets a correction override a stated default. The script announces the default (meets at 4:30 … as usual), then overrides it with But this Friday we will start at 4:45. The correct answer is 4:45.
Why this is not a hearing problem. Mika heard both 4:30 and 4:45 accurately. She had the right information in her head and threw it away. Her stated rule - write the first number I catch - is a decision rule, and it is the thing that is broken. Proof: the same rule produced 6:00 on the library item, where but during test week it closes at 5:30 also overrides a default. Two different scripts, one rule, two errors. That is the diagnosis to give her.
The connector set she must hear as grammar, not decoration.
- as usual / usually → this is the everyday value, not the answer.
- but / however / today / this Friday → the answer is on this side.
- because / so → explanation or result; the answer is almost never here, it is only justified here.
- not Room 1 → the answer is the other member of the pair, Room 2.
Note-taking routine (one line per item).
- Before the first playing, read the question and underline the question word (what time / where / who). You now know what kind of number or place to hunt for.
- Write every number you hear in a left column, with one symbol: △ for 'usual / every day', ○ for 'today / this time'.
- When you hear but, draw an arrow from the △ number to the ○ number and box the ○ number. The box is your answer.
- Never erase. Two numbers on the page let you re-check during the second playing; one number leaves you nothing to check.
- On the second playing, verify only the boxed value. Do not re-listen to the whole script - that is how students run out of time on later items.
2. Mika also blanks out when she misses the opening line. Using this same script, show what she can still recover from the middle, and what she should do in the pause before the second playing.

What she loses by missing the first sentence. She loses the topic and the default value (science club, Friday, 4:30). She does not lose the answer, because the answer lives after But: this Friday we will start at 4:45 and Room 2, not Room 1. Both key facts survive in the second half of the script.
So the correct behaviour is to keep writing. A blank guarantees zero. A partial answer has a real chance, and the second playing will repair the missing half.
What to write while still confused (placeholder discipline).
- Time: 4:45, with '?' beside it.
- Place: Room 2.
- A one-word note of the topic: 'club'.
Before the second playing (the few seconds that decide the item).
- Do not think about the sentence you missed - it is gone and it is not the answer.
- Re-read the question so you know exactly which fact you are verifying.
- On the second playing, listen for the but clause only, and confirm the boxed value.
What to teach her about the structure. A school announcement in this exam almost always has the shape: usual arrangement → but today → reason → instruction (place, what to bring). The answer sits in the third and fourth parts, never in the first. Once she knows the shape, missing the opening line stops being fatal.
