question 6.
read passage 2: \tree ring discovery\ and answer the following question.
which statement best explains the author’s primary purposes for writing this passage and how those purposes are intended to engage readers?
a. the author’s purposes are to describe and persuade future researchers of nature’s role in recording history for understanding environmental change.
b. the author’s purposes are to persuade and inform readers about dendrochronology’s methods and the importance of preserving tree populations.
c. the author’s purposes are to inform and educate readers on how tree rings indicate wood quality and age so that lumber companies can improve harvesting practices.
d. the author’s purposes are to entertain and inform readers blending scientific facts with a personal discovery narrative.

Explanation:

The passage tells the story of Elena's exploration of tree - ring dating (dendrochronology) and how it helps in understanding past environmental conditions. The author uses a personal - like narrative (Elena's story) to inform readers about the scientific concept of dendrochronology and also to entertain them by presenting a story - like account. Option A is incorrect as there's no persuasion for future researchers. Option B is wrong because the passage isn't about persuading to preserve tree populations. Option C is incorrect as the passage isn't about helping lumber companies. Option D accurately describes the author's purpose of blending a personal - discovery - like narrative (Elena's experience) with scientific facts to both inform and entertain.

Answer:

D. The author’s purposes are to entertain and inform readers blending scientific facts with a personal discovery narrative.
