Questions 31–40. Read the passage and choose the best answer.

What a school recycling audit can tell you
A school audit can help students describe what was collected during a particular event. The group needs to define its categories before counting, use the same method throughout and keep the time period clear. If one team counts individual containers while another estimates a bag’s weight, their totals cannot be compared as if they measured the same thing. Recording both the unit and the method helps readers understand what each number represents.

Material condition can also matter. In paper-recovery systems, food residue, liquids or other unwanted material may reduce the quality of a paper stream. A school project can note that an item was wet or mixed without claiming to know how a local processor would handle it. The students should check the rules of the collection programme they are studying. Accepted items and sorting instructions may differ between programmes, so a symbol on packaging does not by itself establish that a particular school accepts that item.

The audit has limits. A count from one lunch period is a description of that sample, not automatically an estimate of all waste produced by the school each week. A short audit also cannot show what households discard or how a different collection system operates. To make a broader estimate, students would need a longer observation period, a defined sampling method and records from more than one setting.

A useful report states what was counted, how the categories were defined, when the data were collected and what was left out. If the group could not classify an item, it should record the uncertainty rather than silently assigning the item to a convenient category. Clear limits help readers use the results for the question the audit actually addresses.

  1. 31. What is one purpose of defining categories before counting?
    A. To prove that all items are accepted locally
    B. To remove the need to record units
    C. To make the group’s classification method clear and consistent
    D. To estimate household waste from a lunch sample
  2. 32. Why should a report state its unit and method?
    A. To make every result a weight
    B. So readers know what each number represents
    C. To guarantee that the sample covers a full year
    D. So different measurements can be treated as identical
  3. 33. What may reduce the quality of a paper stream?
    A. Food residue or liquid contamination
    B. A clear date on the recording sheet
    C. Sorting the results by material
    D. Counting items during lunch
  4. 34. What does the passage say about recycling symbols on packaging?
    A. They guarantee acceptance by every school programme.
    B. They show how much an item weighs.
    C. They replace the need to check local instructions.
    D. They do not by themselves establish that a school accepts the item.
  5. 35. What can a count from one lunch period describe?
    A. All waste generated by every household
    B. The materials collected in that particular sample
    C. The school’s results for every week of the year
    D. How another collection system operates
  6. 36. What would students need for a broader estimate?
    A. One unlabelled bin and an informal guess
    B. Only a picture of the lunch area
    C. A longer observation period, defined sampling and more settings
    D. A packaging symbol from one item
  7. 37. In paragraph 2, what does “it” refer to in “how a local processor would handle it”?
    A. The school project   B. The paper stream   C. The collection programme   D. The item
  8. 38. The word “discard” in paragraph 3 is closest in meaning to ______.
    A. throw away   B. measure carefully   C. sort by weight   D. record by date
  9. 39. What should students do when they cannot classify an item?
    A. Assign it to a category without noting uncertainty
    B. Remove all other records
    C. Record the uncertainty instead of guessing
    D. Count it in every category
  10. 40. What conclusion does the passage draw about a school recycling audit?
    A. A single school audit proves how all communities recycle.
    B. A well-described audit can answer a limited question when its method and limits are clear.
    C. Local programmes accept the same items everywhere.
    D. Students should avoid recording uncertain items.
