A clearer reading
Keep evidence types separate
Choose a source for the question it can answer.

Review-only course draft. Fictional examples teach reading and arithmetic. Public content is unchanged.
Match a fictional claim to its evidence system without double counting.
In this lesson: concepts, example and checks
Label
What the source claims
Report
A stated tested sample
Experiment
A defined system and comparison
Registration
A separate study record
Begin with the reading task
Ask whether you need a label statement, a sample measurement, a study record or an experimental result. These questions need different checks.
Retain the study system
Write down whether a record describes people, animals or cells, together with the stated preparation and outcome. A model observation is not a direct observation in a different system.
Count identities carefully
In the fictional example, one paper carries two system tags. The tags do not create two independent paper identities. Follow the source rather than counting each placement as new evidence.
Fictional worked example
Fictional evidence-sorting task
Four invented records describe a vendor label, a tested sample, a cell experiment and a study registration. No clinical result or real paper is invented.
- Match a label claim to its original listing.
- Match a sample measurement to its report and method.
- Keep experimental system and registry status separate from human treatment and retail-lot claims.
A cell experiment and a listing do not establish that a retail product works in people.
Keep these actions
- Name the question before choosing a source.
- Preserve the study system and unique identity.
- A source tag is not a product endorsement.
Practice, then revise
Choose an answer and check the explanation. Incorrect answers remain revisable. A check attempt is not mastery or a credential.
Recognize the boundary
A fictional experiment tests cells. Which claim does that directly support?
Read the supported answer and reasoning
Its observed result in those experimental conditions Correct: stay within the experimental system.
Apply it to the example
One fictional paper has both animal and cell tags. How many paper identities are represented?
Read the supported answer and reasoning
One paper with two system tags Correct: retain one identity and both tags.
This is your explicit reading mark. Attempting a check never marks the lesson reviewed automatically.
