Digital SATReading and Writing: Craft and StructureMedium
A scientist is writing a research paper describing a newly discovered biological process. The paper includes a diagram illustrating the sequential steps of the process, labeled 1 through 5. The accompanying text explains each step in detail, using transition words like 'initially,' 'subsequently,' and 'finally.' What is the primary purpose of this text structure?
- ATo describe the chronological order of events in the process.
- BTo compare and contrast different biological processes.
- CTo persuade the reader of the process's innovative nature.
- DTo analyze the causes and effects of the biological reactions.
Show answer & explanationAnswer & explanation
Correct answer: A. To describe the chronological order of events in the process.
The description mentions a diagram with 'sequential steps labeled 1 through 5' and text using 'initially,' 'subsequently,' and 'finally.' These are all strong indicators of a chronological or sequential structure, designed to explain events in the order they occur.
Why the other options are wrong
- B. There's no indication of comparing or contrasting different processes; the focus is on a single new process.
- C. While the process might be innovative, the structure described (sequential steps, chronological transitions) aims to explain, not primarily persuade.
- D. While there might be cause-and-effect relationships within the process, the emphasis on 'sequential steps' and chronological markers points to a primary purpose of describing the order, not just cause-effect analysis.
Text Structure: Sequence/Chronological
A text structure that presents events or steps in the order in which they happened or should happen.
- Uses time-order words (first, next, then, finally).
- Often found in historical accounts, instructions, or scientific processes.
- Helps readers understand a series of events over time.
Memory trick: Organization helps readers follow the plot.
