What is the job of the ring gear in a differential?

The word "stealthy" is being used in this context to describe the manner in which the animals are approaching. It denotes a sense of caution, discreetness, and surreptitiousness. Among the options given:

A. Quiet - While 'quiet' could imply a similar idea, it doesn't fully encompass the sneaky nature of the movements.

B. Secretive - This might imply that the animals have a hidden agenda or are intentionally trying to hide something, which is not specified in the context.

C. Clever - The term 'clever' has more to do with intelligence or cunningness. It doesn't necessarily denote a method of movement.

D. Sneaky - This term similarly conveys the idea of being furtive, sly, or moving without attracting notice, which aligns properly with the context.

Hence, option D. sneaky would be the best replacement for the word "stealthy" without changing its denotative or connotative meaning. The animals were advancing through the snow in a sneaky manner, seeking not to attract attention or alert the scientists to their presence.

The central idea of the text as a whole is how engaging with and appreciating the sounds of nature can give people a deeper understanding and appreciation of their environments. This underlying idea is woven through the narrative of Jacob Job and his work studying and recording soundscapes. The paragraph that best reflects this central idea would be:

B. Paragraph 5

Here's why:

A.Paragraph 1: This paragraph sets the scene and introduces Jacob Job and his work, but it doesn't express the overall significance of the sounds of nature or their value to people which forms the central idea of the article.

B.Paragraph 5: This is the best choice, as it directly speaks to the central theme of the text. In this paragraph, Jacob Job articulates his desire for others to experience and appreciate the captivating sounds of nature. He encourages people to venture outdoors and experience these sounds themselves, which can be done in parks without going to the remote places he does for his research.

C.Paragraph 8: While this paragraph does discuss Job's initial interest in bird sounds and his work in Hawaii, it doesn't fully reflect the central idea of the text, which is about the importance of listening to and appreciating all forms of natural sounds, not just birdsong.

D.Paragraph 12: This paragraph introduces the idea of linking soundscapes to cultural history, which is intriguing but it does not capture the overall theme of appreciating and understanding the environment through sound. It's a part of the narrative, but not the central idea.

The correct answer is D. Paragraph 12.

In this paragraph, the text discusses how Jacob Job recorded cultural sounds at Lewis and Clark National Park to recreate the experiences of the pioneers from the Lewis and Clark Corps of Discovery. Job aimed to bring the history of the place to life through the captured sounds, such as rushing rivers, ocean roar, animal calls, and the sounds of people's activities at Fort Clatsop. The paragraph mentions that these sounds would be used in an educational exhibit for park visitors, emphasizing the central idea that the study of soundscapes helps people understand and appreciate the environments they visit.

The central idea of the text can be determined by analyzing the main themes and messages conveyed throughout the paragraphs. Let's evaluate each option to determine which one best reflects the central idea of the text as a whole.

A. Paragraph 1: This paragraph describes the initial encounter with wolves and coyotes while conducting field research. Although it highlights the excitement of the encounter, it does not capture the essence of the overall message of the text.

B. Paragraph 5: This paragraph emphasizes the importance of getting outdoors and experiencing nature firsthand, as well as the potential for hearing exceptional sounds in parks. While it encourages people to explore and appreciate nature, it does not encompass the central idea of the entire text.

C. Paragraph 8: This paragraph introduces the background and academic projects of Jacob Job, specifically focusing on his passion for birds and their communication in a noisy world. While it provides context about Job's work, it is not the central idea of the entire text.

D. Paragraph 12: This paragraph discusses Job's recording of various sounds to recreate historical experiences at Lewis and Clark National Park. It also mentions the use of these sounds in an educational exhibit for park visitors. This paragraph aligns with the central idea of the text, which is the significance of soundscapes in parks and their ability to create immersive experiences.

Based on the analysis, the correct answer is:

D. Paragraph 12

The word "trickle" as used in the text refers to option C: a slow movement of things little by little. In the given context, Job notes that in other places, birds don't start singing all at once. Instead, one bird would begin singing, then gradually, more and more birds would join the chorus, each adding its song slowly or one-by-one. This description is illustrating the process of a "trickle" effect - a slow, steady, and gradual accumulation or progression of something. Here, the "trickle" pertains to the gradual increase of the birdsong rather than a movement of people (option A), the disappearance of something (option B), or flow of liquid (option D). Hence, the term "trickle" is metaphorically used to depict a gradual build-up of sounds in nature.
