INVESTIGATION 1 OF 6

What did the text actually say?

Separate a textual observation from an inference and give a plausible alternative explanation.

Why learn this? A convincing interpretation begins with details a reader can check, not a guess presented as a fact.

Quick recap: An observation reports a detail; an inference explains what that detail might mean.

1. Try — read before judging

The Last Seat — an original Learn by Doing microfiction. Line numbers refer only to this teaching edition. The narrator does not reveal anyone’s thoughts.

The bus shelter had room for three people if nobody minded wet sleeves.
Mara placed her bag on the only dry seat.
An older passenger stopped beside the timetable and rubbed one knee.
Mara looked up, then pulled the bag closer to her.
Inside it, something clicked against a glass jar.
“I can stand,” the passenger said, though nobody had asked.
Mara lifted the bag onto her lap and sat at the edge of the seat.
A paper label slipped from the bag: RETURN BEFORE SIX.
The passenger sat down without looking at her.
When the bus came, Mara let it go.
She checked the jar, wiped the label dry, and watched the road in the other direction.

2. Predict — make a provisional choice

Why does Mara initially keep the bag on the seat? Record a possibility and the detail you would need to test it. 0 / 16,000 characters · length is a storage limit, not a quality score

3. Experiment — test your reading

Select two lines and label each as an observation, support for an interpretation, or a challenge to it.
Write what each selected line permits you to infer. Keep “the passage says” separate from “I infer.”
Use the final two lines to propose a second explanation for Mara’s behavior. Revise your initial claim.

4. Understand — connect choice and effect

An observation can be checked against the words: Mara puts a bag on a dry seat. “Mara is selfish” is an inference about her character. It might fit the first action, but it must also account for her later decision to make room.

Evidence constrains interpretation without always settling it. The jar and deadline suggest a responsibility outside the bus journey; the text never tells us its contents. A careful reader preserves that uncertainty instead of inventing a fact.

A useful paragraph moves from a claim to a short quotation, explains how the language supports the claim, then considers a detail that complicates it. Several explanations can remain plausible, but not every explanation fits equally well.

Inference: An explanation drawn from details, rather than a directly stated fact.
Textual evidence: Specific words or features another reader can locate and inspect.

Worked example — a possible revision, not the only answer

Before

Mara is rude because she does not want anyone beside her.

After

Mara initially protects the bag’s dry place, but her later movement makes room for the passenger. The jar and deadline suggest that her hesitation may concern a fragile delivery rather than dislike of company.

The revision names actions, accounts for a change and marks the explanation as provisional. It does not claim to know what is in the jar.

5. Apply — make something and try a new case

Your main artifact

Write 120–180 words explaining two possible motives. Quote a detail for each and state what the passage leaves unknown.

Keep your artifact in the working draft above. Suggested lengths help you plan; they do not measure quality.

Unfamiliar passage

Jon left the trophy in its box. At dinner he described every race except his own. Later, his sister found him polishing the empty shelf above his desk.

Offer two interpretations of Jon’s silence. Support each with a detail and identify one question the passage cannot settle. 0 / 16,000 characters · length is a storage limit, not a quality score

Completion means you worked through this investigation. Your interpretation and writing still need judgment using the project rubric; no automatic proficiency score is awarded.
