Source Credibility, Relevance & Corroboration — Practice · Grade 7 English

Chapter: Research & Explanatory Writing

What this practice covers

By the end of Source Credibility, Relevance & Corroboration you should be able to:

10 questions, written answer, each with a worked explanation.

Vocabulary used: corroboration, relevance, evidence, qualification, revision.

Problem 1

Explain corroboration in the assigned reading, distinguishing it from a related idea.
Answer and explanation

Comparison with independently produced evidence that supports or challenges a claim. Credibility concerns whether a source is dependable for a particular purpose. Examine authorship, method, date, access to information, and traceable evidence. A source can be useful for one question and weak for another. Appearance alone does not settle reliability.

Use the model to discuss reasoning after an independent attempt. A different accurate supported response can be correct; written work needs human marking.

Problem 2

Explain why the repost is not a second independent questionnaire and what the letter adds.
Answer and explanation

The repost depends on the same original responses, so a new design does not create independent observations. The letter adds a differently situated access concern. It does not verify every number or represent all nonattendees; the sources support different parts of the inquiry and should be evaluated accordingly.

Use the model to discuss reasoning after an independent attempt. A different accurate supported response can be correct; written work needs human marking.

Problem 3

Evaluate this claim: “A polished website proves accuracy.” Explain a correction in context.
Answer and explanation

This claim is misleading. Read perspective alongside evidence. The resident directly describes a scheduling problem, but cannot count everyone with that problem. The organizer has survey results, but only from a defined invited group. Evaluate these bounded contributions rather than choose a source solely by agreement. The repost depends on the same original responses, so a new design does not create independent observations. The letter adds a differently situated access concern. It does not verify every number or represent all nonattendees; the sources support different parts of the inquiry and should be evaluated accordingly.

Use the model to discuss reasoning after an independent attempt. A different accurate supported response can be correct; written work needs human marking.

Problem 4

Can a source be credible but irrelevant to the task?
Answer and explanation

Yes. An accurate account of a different setting may not support a claim about this trial. Explain the connection rather than assuming that authority alone makes it useful.

Use the model to discuss reasoning after an independent attempt. A different accurate supported response can be correct; written work needs human marking.

Problem 5

Develop an independent response: Explain why the repost is not a second independent questionnaire and what the letter adds. Locate two useful details or choices, and explain one limit or alternative.
Answer and explanation

The repost depends on the same original responses, so a new design does not create independent observations. The letter adds a differently situated access concern. It does not verify every number or represent all nonattendees; the sources support different parts of the inquiry and should be evaluated accordingly.

Use the model to discuss reasoning after an independent attempt. A different accurate supported response can be correct; written work needs human marking.

Problem 6

Answer this transfer question: Can a source be credible but irrelevant to the task? Test your answer against a second detail or a fresh sentence, explaining whether it needs qualification.
Answer and explanation

Yes. An accurate account of a different setting may not support a claim about this trial. Explain the connection rather than assuming that authority alone makes it useful.

Use the model to discuss reasoning after an independent attempt. A different accurate supported response can be correct; written work needs human marking.

Problem 7

Explain corroboration in your own words and give an example from the assigned reading or a fresh sentence.
Answer and explanation

Comparison with independently produced evidence that supports or challenges a claim. The unit case offers this example to examine: The repost depends on the same original responses, so a new design does not create independent observations. The letter adds a differently situated access concern. It does not verify every number or represent all nonattendees; the sources support different parts of the inquiry and should be evaluated accordingly. Identify the wording or choice that fits the term. A different accurate example is acceptable.

Use the model to discuss reasoning after an independent attempt. A different accurate supported response can be correct; written work needs human marking.

Problem 8

Explain relevance in your own words and give an example from the assigned reading or a fresh sentence.
Answer and explanation

The relationship between evidence and the specific question being investigated. The unit case offers this example to examine: The repost depends on the same original responses, so a new design does not create independent observations. The letter adds a differently situated access concern. It does not verify every number or represent all nonattendees; the sources support different parts of the inquiry and should be evaluated accordingly. Identify the wording or choice that fits the term. A different accurate example is acceptable.

Use the model to discuss reasoning after an independent attempt. A different accurate supported response can be correct; written work needs human marking.

Problem 9

Correct the misleading statement “A polished website proves accuracy.” and explain a detail that makes your correction necessary.
Answer and explanation

Credibility concerns whether a source is dependable for a particular purpose. Examine authorship, method, date, access to information, and traceable evidence. A source can be useful for one question and weak for another. Appearance alone does not settle reliability. The repost depends on the same original responses, so a new design does not create independent observations. The letter adds a differently situated access concern. It does not verify every number or represent all nonattendees; the sources support different parts of the inquiry and should be evaluated accordingly.

Use the model to discuss reasoning after an independent attempt. A different accurate supported response can be correct; written work needs human marking.

Problem 10

Correct the misleading statement “Several copies of one report are independent corroboration.” and explain a detail that makes your correction necessary.
Answer and explanation

Follow a claim to its origin. A reposted chart based on Source A is not a second independent survey. Compare methods and source chains rather than counting web pages. If several pages repeat one record, identify the record they share. The repost depends on the same original responses, so a new design does not create independent observations. The letter adds a differently situated access concern. It does not verify every number or represent all nonattendees; the sources support different parts of the inquiry and should be evaluated accordingly.

Use the model to discuss reasoning after an independent attempt. A different accurate supported response can be correct; written work needs human marking.
