What RI.7.3 Means in Plain English

Seventh graders show how the people, events and ideas in a nonfiction text push on one another. In a passage on London’s 1854 cholera outbreak, a popular theory about bad air steered officials, while one doctor’s map got a pump shut down.

Sixth graders (RI.6.3) followed how a text introduces one person, event or idea and builds it out with examples. Seventh grade puts two or three in play and asks what each did to the others. Eighth grade (RI.8.3) studies how texts link or contrast them, using comparisons or categories.

RI.7.3 I Can Statements

I can explain how an idea shaped what a person or group did.
I can explain how a person changed the course of an event.
I can trace a chain of influence through a nonfiction text.

RI.7.3 Worked Example

An idea, a doctor and two events all act on one another here, and the weak answer retells them in order without saying what changed what.

Read the Story

In the 1850s, most doctors in London believed cholera spread through “miasma,” foul-smelling air from rotting waste. Because of that idea, officials worked to remove smells, and few of them thought to test the drinking water.A doctor named John Snow disagreed. He suspected that cholera spread through water polluted with sewage.When cholera killed hundreds of people around Broad Street in 1854, Snow marked each death on a map. The deaths clustered around one public water pump. Workers at a nearby brewery, who drank beer and water from the brewery’s own well, were largely spared.Snow showed his evidence to local officials, and they agreed to remove the pump’s handle. Many experts still rejected his theory about water.In the hot summer of 1858, the River Thames smelled so bad that Parliament approved a huge sewer system to carry the stink away. The sewers also kept sewage out of the drinking water, and London’s last major cholera outbreak came in 1866. The idea of bad air had helped beat cholera for the wrong reason.

A short passage written for this page.

Question: How did the idea of miasma and John Snow each influence the events in this passage?

Not Yet“First people believed in miasma. Then John Snow made a map of the cholera deaths and the pump handle was removed. Later London built sewers and cholera ended.”Every event is right and in order, but the answer never says what caused what. It reads as a timeline, so the most interesting interaction, a wrong idea leading to the sewers, disappears.

Meets the Standard“The miasma idea steered officials toward fighting smells, so few tested the water, and it is also why Parliament built the sewers in 1858. Snow’s different idea about water led him to map the Broad Street deaths, and his evidence got the pump handle removed, even though experts kept doubting him. The twist is that the miasma idea produced sewers that cut off cholera’s real path, so a wrong idea and a right one both changed what happened.”Each sentence names what did the influencing and what changed because of it. The answer also catches the interaction the author saves for the last line.

Question Stems to Use

What did this idea lead people to do, or not do?How did this person change the course of events?Did an event change anyone’s mind? Whose?Which interaction would surprise someone who read only the first paragraph?Can you draw the chain: idea, then person, then event?

Common Mistakes with RI.7.3

A timeline instead of an analysis

“First…, then…, later…” with no word showing cause

Try this: Ban “then” for this task and require “because,” “led to” or “so” in every sentence that connects two parts of the text.

Arrows pointing only one way

Only how Snow affected events, never how the miasma idea shaped officials or the sewers

Try this: Have students draw arrows between the idea, the person and each event, and ask for at least one arrow leaving the idea.

Turning one person into the whole story

“John Snow stopped cholera in London.”

Try this: Ask what the text says actually ended the outbreaks, then have students check whether their claim about the person matches it.

Quick Check

How did the miasma idea affect what London officials did?
They worked to remove bad smells, and few of them thought to test the drinking water.
What evidence did John Snow gather, and what did officials do with it?
His map showed the deaths clustered around one pump, and brewery workers who drank from their own well were largely spared. Officials removed the pump’s handle.
Why does the passage say the bad-air idea helped beat cholera “for the wrong reason”?
Parliament built the sewers to carry away the smell, but they worked against cholera because they kept sewage out of the drinking water.
