71. Students are collecting research for an informational report and have recorded their notes on index cards. To most efficiently use the cards, students should group the cards together

Answer: C

Explanation:

Students should group the cards together using topic headers to sort by related information.

Organizing index cards by using topic headers allows students to categorize their notes in a logical manner, making it easier to locate and reference related information when compiling their report.

A) random piles of ten

Creating random piles of ten does not provide any meaningful organization or categorization of the information. This method would likely lead to confusion and inefficiency when trying to reference specific notes, hindering the research process.

B) according to source

While grouping notes according to the source can help in tracking where information came from, it does not facilitate a coherent flow of related ideas. This method may be useful in some contexts, but it fails to emphasize the connections between topics that are crucial for structuring an informational report.

C) using topic headers to sort by related information

Sorting index cards by topic headers allows students to organize their notes around central themes, making it easier to see how different pieces of information relate to one another. This method enhances comprehension and supports the logical progression of ideas in the final report.

D) based on what page of the source the information was found

Organizing cards by the page number from which information was drawn may provide a reference point, but it does not create a framework for understanding the relationships between different pieces of information. This approach can be inefficient as it may scatter related ideas across various cards without a clear thematic structure.

Conclusion

Grouping index cards using topic headers is the most effective way to organize research notes, as it fosters connections between related information. Other options either lack organization or focus on irrelevant attributes, which can complicate the writing process rather than streamline it. Ultimately, option C provides the clarity and structure needed for an effective informational report.
