In order to determine the correct format for the reading section, it would depend on the specific test or assessment you are referring to. Different exams or reading assessments may have different formats. However, I can provide some information about the general formats commonly used in reading sections.

Typically, reading sections are divided into multiple parts, and each part may consist of various types of passages and questions. The specific order may vary, but two common formats are as follows:

Format 1:
- Part 1: Vocabulary questions
- Part 2: Short passage with accompanying questions
- Part 3: Longer passage with accompanying questions

Format 2:
- Part 1: Vocabulary questions
- Part 2: Two short passages with accompanying questions
- Part 3: Two shorter passages with accompanying questions

Please note that this is a generalized explanation, and actual exams or assessments may have variations in the format. It is best to refer to the specific instructions or guidelines provided by the exam or assessment provider to find the exact format and sequence of the reading section.
