B2 • About 30 minutes. Compare the same unit across times or service points. Choose intensifiers justified by the displayed difference. Describe gradual and linked change without inventing causality. Write a concise data-informed everyday update.

Waiting time: 10:00 = 5 min; 11:00 = 10 min; 12:00 = 20 min. 11:00 is twice 10:00; 10:00 is half 11:00. Queue and wait rise together here; cause is unproved. — Instructional visual. A selectable-text equivalent appears in the resource.

Read the café observation log

An organiser recorded six observations at a fictional community pop-up café. Each row gives the time, the number of people waiting, the approximate wait in minutes and the number of empty seats. The observations cover one morning only. They do not record staffing changes, order sizes or the time spent preparing each drink.

Time	Queue (people)	Wait (minutes)	Empty seats
10:00	4	5	20
10:30	6	6	16
11:00	8	10	12
11:30	12	15	8
12:00	16	20	4
12:30	18	22	2

Unit audit: people are a count, minutes are a duration, and empty seats are another count. Compare waits with waits and queues with queues. The increasing queue and wait occur together in this log, but the log does not identify a cause. A claim about every café or every future morning would exceed the evidence.

Decide what your comparison says

Degree words such as slightly or much describe the size of a difference without giving an exact ratio. Some choices are matters of reasonable judgement. Ratio language, by contrast, can be checked directly: the ten-minute wait at eleven is twice the five-minute wait at ten. Keep the comparison direction visible.

Repeated comparatives describe gradual change. Linked comparatives describe two changing quantities together. Neither structure is a scientific explanation. In your final update, give the important numbers, use a few well-chosen comparisons and propose one extra observation that would help explain the pattern next time.

How different?

Where the prompt requests a degree, several natural modifiers may be accepted. Do not mistake a style preference for a unique mathematical answer.

1 The wait rises from 5 to 6 minutes. Choose slightly, a little or a bit: “It is ___ longer.” Your answer

Answer and explanation

slightly

Also accepted: a little; a bit

Slightly, a little and a bit all express a small increase in this frame. Giving the one-minute difference is more precise.

2 The wait rises from 5 to 20 minutes. Choose much, far or a lot: “It is ___ longer.” Your answer

Answer and explanation

much

Also accepted: far; a lot

Much, far and a lot are all reasonable large-difference modifiers here. The observed increase is fifteen minutes.

3 Choose the grammatical phrase for the growing crowd.

Choose one answer.

much more crowded very more crowded much crowded than

Answer and explanation

much more crowded

Much can modify more crowded. Very normally modifies the plain adjective, as in very crowded.

4 Choose the grammatical degree phrase.

Choose one answer.

The earlier service seemed much good. The earlier service seemed very good.

Answer and explanation

The earlier service seemed very good.

Very modifies good. This is a grammar judgement, not a claim that the log independently measured service quality.

Read the ratios

Use the two named rows and keep the unit fixed.

5 Use an as…as comparison. At 11:00 the wait is 10 minutes; at 10:00 it is 5. “At 11:00 the wait was ___ at 10:00.” Your answer

Answer and explanation

twice as long as

Also accepted: two times as long as; 2 times as long as

10 ÷ 5 = 2. This compares waiting duration, not speed.

6 Use an as…as comparison to reverse the direction: “At 10:00 the wait was ___ at 11:00.” Your answer

Answer and explanation

half as long as

Also accepted: one half as long as

5 ÷ 10 = 0.5. The comparison base is now the ten-minute wait.

7 Compare 12:00 with 10:00: “The 20-minute wait was ___ as long as the 5-minute wait.” Your answer

Answer and explanation

four times

Also accepted: 4 times

20 ÷ 5 = 4. Both figures are in minutes, so the ratio is meaningful.

8 At 11:30, 12 people waited; at 10:30, 6 waited. “There were ___ as many people at 11:30.” Your answer

Answer and explanation

twice

Also accepted: two times

12 ÷ 6 = 2. This time the compared quantity is the number of people.

9 Choose a repeated-comparative description of the queue.

Choose one answer.

The queue became longer and longer. The queue became more longer and more longer.

Answer and explanation

The queue became longer and longer.

The observations rise from four to eighteen people. Longer already contains comparative marking.

10 Complete: “The café became ___ and more crowded.” Your answer

Answer and explanation

more

More and more crowded is the repeated-comparative pattern for crowded in this task.

11 Complete with the comparative form of long: “In these observations, the longer the queue grew, the ___ the wait became.” Your answer

Answer and explanation

longer

Both queue count and waiting duration increase in the log. The phrase describes their association during the stated period.

12 Complete: “The busier the café became, the ___ empty seats there were.” Your answer

Answer and explanation

fewer

Empty seats fall from twenty to two. Fewer is appropriate for a countable plural.

13 Repair: “At eleven, the wait was twice as fast as at ten.”

Choose one answer.

At eleven, the wait was half as long as at ten. At eleven, the wait was twice as long as at ten.

Answer and explanation

At eleven, the wait was twice as long as at ten.

The duration rises from five to ten minutes. Faster compares speed and points in the wrong direction here.

14 Repair the mismatched units: “The queue was longer than ten minutes.”

Choose one answer.

The wait was longer than ten minutes. The queue was longer than ten seats.

Answer and explanation

The wait was longer than ten minutes.

Minutes measure waiting duration. Seats and people are counts, not time units.

15 Replace ambiguous ratio wording “The wait was two times more at eleven.”

Choose one answer.

The wait at eleven was more twice. The wait at eleven was twice as long as at ten: ten minutes rather than five.

Answer and explanation

The wait at eleven was twice as long as at ten: ten minutes rather than five.

The explicit as-long-as frame and the figures make the intended two-to-one ratio clear.

16 Repair: “Long queues always cause long waits.”

Choose one answer.

During this morning’s observations, longer queues were accompanied by longer waits. Long queues prove that the staff worked slowly.

Answer and explanation

During this morning’s observations, longer queues were accompanied by longer waits.

The log shows association over one morning. It contains no evidence about universal causes or staff effort.

Write, compare and revise

Your turn · self-review

Independent writing

Write your own response first, then compare the model and use the self-review checklist below. The model is one possible answer, not a script to copy.

Practice only. Your writing stays on this page; it is not submitted or saved.

1Write a 100–120-word update for the organiser. Compare two periods, use one exact ratio and one linked or gradual-change structure, and propose one additional observation to collect next time. Do not claim a proven cause.
Model answer and explanation
The café became busier and busier during the recorded morning. At ten, four people were waiting and the wait was five minutes. By eleven, the queue had doubled to eight people, and the ten-minute wait was twice as long as at ten. At noon, sixteen people were waiting and only four seats were empty. In these observations, the longer the queue grew, the longer the wait became. This does not show that queue length alone caused the delay. Next time, we could also record how many staff members are serving at each observation, so we can compare the pattern with another relevant detail.

Self-review and transfer

The model gives a two-to-one wait ratio and restricts the linked comparison to the observations. It proposes a staffing count as new information to collect, without claiming staff numbers caused the recorded change. Check every pair of units, the direction of each ratio, the time window and the difference between an observation and a cause. A different suitable next observation might be order size or service-point availability.
