Six Brackets in a Host-Family Email
Hana has drafted an email to her host father, Mr Tanaka, and left six words in brackets. Her teacher has asked her to choose one word for each gap and to be ready to explain the grammar that decides it.
'Dear Mr Tanaka, I (1) [live / have been living] in Akita for three years, but I (2) [did not visit / have not visited] the Nebuta festival until last August. My sister, (3) [who / which] is studying in Tokyo, came home for it. On the last night the streets were (4) [so / such] crowded that we could hardly walk. Next year my teacher suggested that we (5) [go / went] together and take the early train, and I am looking forward to (6) [hear / hearing] from you about your summer plans. Best wishes, Hana'
The teacher adds one warning: 'One of these gaps is not really a right-or-wrong choice at all. Two of them lose marks for the same underlying reason. Find the warning gap first, then explain it.'
1. Choose the word for gaps 1–6 and give the grammar trigger for each choice in a short phrase.

(1) Either is correct - this is the warning gap. 'I have been living in Akita for three years' stresses an activity continuing up to now; 'I live in Akita for three years' is unnatural in English, but 'I live in Akita' with a duration phrase is acceptable in the simple present when the situation is presented as permanent. The safe exam answer is have been living (present perfect continuous with 'for' + duration), and the reasoning to write is 'both possible; the continuous emphasises temporary duration'.
(2) did not visit. 'Until last August' sets a finished boundary in the past, and the present perfect cannot be used with a definite finished past time. Trigger: past time marker, not current relevance.
(3) who. Non-defining relative clause about a person; 'which' cannot refer to a person, and the commas forbid 'that'.
(4) so. 'So' + adjective ('so crowded'); 'such' needs a noun phrase ('such a crowd'). Trigger: word class after the gap.
(5) go. After 'suggested that', English uses the base form (mandative subjunctive), or 'should go' in British style. Trigger: verbs of suggestion and demand.
(6) hearing. A preposition ('looking forward to') takes a gerund. Trigger: preposition + -ing.
2. Hana later writes: 'I have visited the Nebuta festival until last August.' Explain why this fails, and rewrite it two ways that mean different things.

Why it fails. 'Until' marks the end point of a state or activity that continues (wait until six, stay until Monday) or the end point of a negative ('did not visit until August'). 'Have visited' is an achievement - a completed event, not a continuing state - so it cannot be stretched up to a boundary. There is also a clash of time frames: present perfect looks at a period open to now, while 'last August' is a closed past point.
Rewrite A (before that date, nothing happened): 'I did not visit the Nebuta festival until last August.' Meaning: last August was the first time; before that, no visits.
Rewrite B (nothing since that date): 'I have not visited the Nebuta festival since last August.' Meaning: the only visit was last August, or the visits stopped then.
The point being tested: 'until' and 'since' are not interchangeable, and swapping them changes which side of the date the information sits on. Both rewrites keep the date and reverse the meaning, which is exactly the discrimination the item rewards.
3. The teacher said two gaps lose marks for the same underlying reason. Which two, and what is that reason?

Gaps 4 and 6. Both are decided by the word class that the grammar slot requires, not by meaning or by translation.
In gap 4, the slot after 'were' and before the adjective 'crowded' needs an adverb of degree ('so'); 'such' is a determiner and must be followed by a noun phrase. In gap 6, the slot after the preposition 'to' needs a noun-like element, so the gerund 'hearing' is required; the bare infinitive cannot follow a preposition.
Shared reason: students choose by what the Japanese equivalent 'feels' like, and Japanese has no separate 'so/such' pair and no gerund after prepositions, so both errors survive translation. The reliable method is to look at the words on either side of the gap and ask what class of word can stand there.
Contrast with gap 1, which is a genuine choice of nuance rather than a rule. Distinguishing 'rule-governed' gaps from 'meaning-governed' gaps is the skill the item is measuring.
