To effectively use the survey as evidence in support of using genetically modified ingredients in school cafeterias, the writer would need to determine:
- The methods used by the survey author to conduct the survey - This will help assess the reliability and validity of the data collected.
- Whether the survey reflects the experiences of most people - Understanding whether the survey results are representative of a broader population will strengthen the argument.
These two factors are critical in evaluating the credibility and applicability of the survey results to the argument being made.
