Part 2: Reading comprehension

Passage A

A training office accepts applications online. After an applicant submits the form, the office sends a confirmation. Applicants should keep the official link, submission date, confirmation and later messages in one record. If no confirmation arrives, the applicant should review the official instructions and use the contact channel printed on that page. The tracker does not decide whether an applicant is accepted.

7. What is the main purpose of Passage A?

  1. Explain how to keep an application record
  2. Promise admission after a form is sent
  3. Compare training wages
  4. Describe classroom tools

8. What should the applicant do if no confirmation arrives?

  1. Mark the application accepted
  2. Submit through an unrelated page
  3. Review the official instructions and use the listed contact channel
  4. Delete the submission date

9. Which conclusion is not supported by Passage A?

  1. The official link belongs in the record
  2. Later messages should be saved
  3. The tracker does not decide acceptance
  4. A submitted form guarantees admission

Passage B

Before buying tools, Maya asks the employer for the current list. The employer identifies which required protective equipment it provides and which ordinary personal items are not on the list. Maya leaves every cost field blank until she receives written instructions. She saves the source and the date of the answer.

10. Why does Maya leave the cost fields blank?

  1. She has already bought every item
  2. She is waiting for written instructions
  3. The employer banned all tools
  4. The worksheet cannot store numbers

11. What evidence does Maya save?

  1. The source and date of the answer
  2. A guess from another applicant
  3. An undated shopping list
  4. Only the cheapest item

12. Which statement best summarizes Passage B?

  1. Buy a full kit before asking anyone
  2. Assume all protective equipment is personal
  3. Confirm the current list before spending
  4. Use the same list for every employer

Answer key and one-sentence explanations

1. B, 6. Subtract 7 from both sides, then divide 18 by 3.
2. C, 21. Substituting 6 gives 4 times 6 minus 3, which is 21.
3. D, 23. The sequence increases by 4 each time.
4. C, 11. Solving x + y = 18 and x = y + 4 gives y = 7 and x = 11.
5. B, 45. Each record takes 4.5 minutes, so ten take 45 minutes.
6. D, 11. Expanding gives 3x – 6 = 2x + 5, so x = 11.
7. A. The passage explains which facts to retain and what to do when confirmation is missing.
8. C. The stated next step is to use the instructions and contact channel on the official page.
9. D. The passage explicitly says the tracker does not decide acceptance.
10. B. Maya waits for written instructions before estimating costs.
11. A. The final sentence names the source and date as saved evidence.
12. C. The sequence of actions supports confirming the current list before spending.
