ISEE Lower Level: Reading Comprehension › Author's Purpose
The author's primary reason for mentioning that each species has a unique flashing pattern is to
prove that fireflies have one of the most advanced forms of animal communication.
suggest that it is difficult for scientists to study all the different firefly species.
emphasize the importance of light as a precise tool for firefly reproduction.
question whether different species of fireflies are able to understand each other.
Explanation
The correct answer is C. Mentioning the unique patterns for each species highlights how specific and important the light signals are for attracting the correct mate, which is essential for reproduction. (A) is incorrect as the passage does not discuss the challenges scientists face. (B) makes a claim of being the "most advanced," which is an exaggeration not supported by the text. (D) is incorrect because the passage implies the unique patterns are to prevent other species from understanding, not to question if they can.
Why does the author state that the “no cutting, gluing, or marking” rule makes origami “both a challenge and a marvel”?
To list all the essential supplies that are needed to start doing origami.
To highlight the skill required and the amazing results produced within these limits.
To suggest that these rules should be changed to make origami easier for beginners.
To explain why origami is not considered a serious art form by many people.
Explanation
The correct answer is C. By calling the constraint a "challenge," the author points to the difficulty and skill involved. By calling it a "marvel," the author emphasizes how impressive the final sculptures are, given the strict limitations. (A) is incorrect as the author presents the rule as a key feature, not something to be changed. (B) is an unsupported claim; the passage treats origami as a legitimate art and science. (D) is incorrect because the point is about what is not used, rather than what is needed.
This passage was most likely written to
instruct readers on how to organize a protest.
entertain readers with a story of adventure.
analyze the failures of the British Empire.
inform readers about a key historical event.
Explanation
The correct answer is C. The passage presents factual information about a specific historical event (the Salt March) in a clear, narrative style. Its purpose is to inform. (A) is too broad; the passage focuses on one event, not a full analysis of the British Empire's failures. (B) is incorrect because the passage describes a protest but does not provide instructions on how to organize one. (D) is incorrect because while the march was an adventure for its participants, the tone of the passage is historical and informative, not primarily entertaining.
