4.A Selecting and Combining Apt Source Material (CLE-1.P)

Selecting apt source material means pulling the one sentence each source offers your argument, including a single conceded line from an opponent, instead of summarizing every source in full.

A source is not a block to drop in whole. It is a mine with maybe one usable vein. Your thesis defines what counts as usable: a statistic, a concession, a sharp phrase, anything that makes your specific claim stand up. Everything else in that source, including its overall argument, its examples, its tone, can be ignored. This is why three sources used hard beat six sources used thin. Six quick citations read as a list, each one gestured at and dropped. Three sources mined for exactly what your reasoning needs read as a mind working, because you stay with each one long enough to explain what it does for your claim and why.

The sharpest move is pulling a concession from a source that argues against you. If a source spends four paragraphs opposing a fee increase but admits in one line that the current system leaves thousands of households unbilled, that single sentence is worth more than the same fact stated by an ally, because the opponent had every reason not to grant it. Combining sources works the same way: take a statistic from one and a concession from another and fuse them into a single sentence, so the concession does not cancel the claim but sets up exactly why the claim still holds.

This is why the node-and-edge picture of sources matters. Each source is a position in a conversation, agreeing or disagreeing with others and with your thesis, which is itself a node you are adding. Selecting apt material means choosing which edges, which exact points of agreement or friction, your essay will draw out rather than restating every node's whole position.

Key terms

Synthesis
Combining material from multiple sources into one original line of reasoning rather than summarizing each separately.
Concession
A point a source admits even though it works against that source's overall argument.
Apt source material
The specific sentence, statistic, or phrase from a source that directly serves the writer's claim.
Node and edge mapping
Treating each source as a position and each agreement or disagreement between sources as a connecting relationship.

  3. Worked exampleShow me how to pull one usable line out of a source that mostly argues against you.
  4. Common mistakeWhy isn't the count of sources cited what a synthesis score is actually measuring?
