Question 1

1. It distracts from the meaning by adding sounds that replace the author’s words.
2. It highlights emotional shifts, helping listeners feel the loneliness and excitement more strongly. (correct answer)
3. It proves the events happened exactly as described because the voice sounds sincere.
4. It makes the story mainly about soccer skills rather than adjusting to a new place.

Explanation: This question tests SL.7.2—analyze main ideas and supporting details in diverse media/formats (visually, quantitatively, orally). Media present ideas differently: AUDIO (podcasts, speeches, interviews—through voice/pacing/sound, details through facts/quotes/examples heard), VIDEO (documentaries, news, educational—through images/demonstrations/graphics, details through footage/interviews/data visualizations), MULTIMEDIA (websites, digital presentations—across text/images/video, details from multiple formats), PRINT+VISUAL (articles with photos/diagrams—text supported by visual evidence). The podcast uses audio-specific elements—voice modulation (quieter for loneliness, faster for excitement) and selective background music—to enhance emotional content of the memoir. Choice B correctly identifies how these sound and pacing choices highlight emotional shifts, helping listeners experience the feelings more strongly than text alone could convey. Choice A incorrectly suggests distraction, C makes false claims about proof, and D misinterprets the story's focus. Audio formats uniquely use voice qualities, pacing, and sound design to convey emotional nuance and emphasize key moments in narrative content.

Question 2

1. The upbeat background music, the row of clean blue bins, and the bright colors used in the video make recycling look appealing and organized to viewers.
2. The narration describing why some items are rejected, the footage of the food-stained box removed on the belt, and the worker's warning about spoiled batches all point to the same idea. (correct answer)
3. The narrator's statement that recycling is important, the footage of trucks driving toward the sorting facility, and the shots of workers arriving support a message about recycling's value.
4. The worker's explanation of a daily job schedule, the narrator's closing thanks to viewers, and the ending credits give the video a friendly, personal feeling for the audience.

Explanation: The main idea is that contamination makes recycling less effective, so the best answer is the set of details that all point to that single idea. The narration about why items get rejected, the footage of the stained box being removed, and the worker's warning about spoiled batches each support the idea in a different format—words, images, and an interview working together. The choice about upbeat music, clean bins, and bright colors describes the video's mood and look, not evidence about contamination. The choice about recycling being important, trucks heading to the facility, and workers arriving supports a general point about recycling's value, not the specific idea that contamination is a problem. The choice about a job schedule, closing thanks, and credits describes friendly, wrap-up details that have nothing to do with why recycling fails. Only one set of details actually backs the stated main idea.

Question 3

1. The footage and captions let viewers see examples and definitions at the same time, making the problem easier to understand. (correct answer)
2. The clip is convincing mainly because documentary videos always present information that is completely free of bias.
3. The main idea is that traveling by boat is the most reliable way for scientists to reach and study the ocean.
4. The captions are added so that viewers can ignore the scientist's spoken words and read everything they need instead.

Explanation: The best answer explains how the video format itself helps: viewers watch real footage of plastic in the sand while reading captions that define "microplastics," so they see examples and definitions together. Combining images and text makes an abstract idea concrete and easier to grasp than words alone. The choice about documentaries always being completely free of bias is wrong because no format is automatically unbiased—videos still make choices about what to show and say. The choice about boats being the most reliable way for scientists to reach the ocean misidentifies the main idea; the clip is about plastic pollution, not travel methods. The choice claiming captions let viewers ignore the scientist is wrong because captions are meant to support and reinforce the narration, not replace it—the spoken explanation and the on-screen text work together. Only the first choice actually describes how the video's combination of visuals and text strengthens understanding of the main idea.

Question 4

1. The brief clip of crackling fire that the station plays to set an urgent mood before the discussion. (correct answer)
2. The list of clear, step-by-step actions that families can take to prepare for the wildfire season.
3. The surprising statistic showing that most dangerous home fires actually get their start from embers.
4. The firefighter's carefully worded definition explaining what embers are and why they spread flames.

Explanation: The right answer is the crackling fire clip. A sound effect is something only an audio format can deliver—text on a page cannot make you hear fire—so it uses sound to grab attention and set an urgent mood around the topic. That makes it the element most specific to audio. The step-by-step list of actions families can take is useful information, but you could read that exact list in an article or on a poster, so it isn't tied to audio. The statistic about home fires starting from embers is a strong supporting detail, yet a number like that works just as well printed in a paragraph, so it isn't format-specific either. The definition of embers is content the firefighter delivers with words; it explains the topic but could appear in any format, spoken or written. Only the sound clip depends on being heard, which is why it best fits an audio interview.

Question 5

1. Maya, because she names an idea from the video and points to a detail she saw the kids in the footage smiling about biking.
2. Chen, because he states a central message and ties it to facts and an interview from the video. (correct answer)
3. Maya, because she uses only what appears on screen, and a main idea should always come from images rather than spoken content.
4. Chen, because he mentions pollution, and a topic named by an interviewed expert is what a viewer should treat as the main idea.

Explanation: Chen has the stronger analysis. He names a clear central message—that biking to school can cut traffic and pollution—and then backs it up with real evidence from the video: the reporter's facts about fewer cars near the school and the principal's interview about safer drop-off lines. That is exactly what identifying a main idea with supporting details means. The choice praising Maya for pointing to smiling kids mistakes a surface impression for the message; a smiling face is a detail, but 'biking is fun' isn't the point the video is actually making. The choice claiming a main idea should always come from images rather than spoken words uses a wrong criterion—in a news video, spoken facts, data, and interviews carry just as much meaning as pictures. The choice that treats any topic named by an expert as the main idea also misreads: an interview supports a main idea, but simply hearing 'pollution' mentioned doesn't make it the central message. Strong media analysis means finding the central point and confirming it with specific evidence from the format, not reacting to one visual or one word.

Question 6

1. Toilet leaks can be found by adding food coloring to the tank and watching whether the color appears in the bowl.
2. Water conservation at home is possible through simple habits and quick checks for leaks. (correct answer)
3. Wasting water at home is mostly caused by hidden leaks that families cannot notice without special testing equipment.
4. Saving water requires expensive plumbing upgrades that only trained professionals can safely install in a home.

Explanation: The page pulls together three parts that all point to one message: everyday water saving at home is doable through simple habits and easy leak checks. The text explains that leaks matter, the video demonstrates an easy way to check for one, and the checklist lists small daily actions—so the choice about simple habits and quick checks captures what all three parts share. The food-coloring choice describes only one detail from the video, not the overall message of the whole page. The choice claiming leaks are the main cause of waste and need special equipment misreads the page, which stresses easy, at-home actions and a no-cost coloring test. The choice about expensive upgrades and professionals contradicts the page entirely, since every action shown is something a person can do themselves for free. A main idea has to cover the whole page, not just one piece or an idea the page never supports.

Question 7

1. The video shows volunteers using hammers and wood to build the raised beds where crops will grow.
2. On-screen text announces that 24 garden plots are available for interested community members to claim.
3. A volunteer says extra vegetables from the garden will be donated to a local food pantry. (correct answer)
4. On-screen text advertises the free Saturday workshops that will teach neighbors gardening skills.

Explanation: The main idea is that the garden helps people in the neighborhood get healthy food. The detail about donating extra vegetables to a local food pantry directly supports this, because a food pantry serves people who may not otherwise be able to afford fresh food—so the garden clearly improves food access. The detail about volunteers building raised beds only shows how the garden is being constructed, not who benefits from its food. The detail about 24 plots being available tells you the garden's size and who can join, but joining a plot is about participation, not about reaching people who lack healthy food. The detail about free Saturday workshops shows the garden shares gardening skills, which is helpful but is about teaching, not directly about getting food to people who need it. When you analyze a news video, connect the detail to the exact main idea being asked about—here, that means finding the detail that shows food actually reaching the community.

Question 8

1. It shows Amir speaking with confidence, which lets viewers trust his claims without needing him to give supporting evidence.
2. It uses audience interaction and visible slides to make the steps memorable and concrete. (correct answer)
3. It captures Amir’s exact tone of voice, which guarantees his ideas are more accurate than the same points printed in an article.
4. It adds a personal school story, which mainly entertains viewers rather than clarifying the steps for spotting misinformation.

Explanation: The right answer is that the video uses audience interaction and visible slides to make the steps memorable and concrete. When Amir asks people to raise their hands and shows a slide listing “Pause,” “Check the source,” and “Look for another report,” the format does something a text-only article cannot: it involves the audience and reinforces the steps with visuals. That is exactly how video presents ideas well. The choice about Amir speaking confidently is wrong because confidence on camera does not replace the need for evidence—a speaker can sound sure and still be incorrect. The choice about his tone of voice is wrong because hearing someone’s voice does not make claims more accurate; accuracy depends on the content, not the delivery. The choice about the personal school story is wrong because the story actually supports his point by giving a real example, so calling it mainly entertainment misreads its purpose. Only the keyed answer identifies a real strength of the video format for presenting these ideas.

Question 9

1. A pediatrician explains that not getting enough sleep can hurt teens' attention and memory during the school day.
2. Later school start times can help teens get enough sleep and improve school outcomes. (correct answer)
3. Most 7th graders in the local survey get fewer than 8 hours of sleep on school nights.
4. One district that moved its start time to 8:30 saw fewer tardies among its students.

Explanation: The podcast's main idea is that schools should start later so teens can get enough sleep and do better in school. Everything Keisha includes—the survey numbers, the district example, and the doctor's interview—works together to support that one big claim, so the choice about later start times helping teens sleep and improve outcomes is the best answer. The choice about the pediatrician explaining how missing sleep hurts attention and memory is only one piece of supporting evidence, not the overall point. The choice about most 7th graders getting fewer than 8 hours is just the survey detail that helps prove the argument. The choice about one district seeing fewer tardies after moving to 8:30 is another single supporting example. When you analyze audio like a podcast, ask what all the spoken evidence and clips are added up to prove, not which single fact stands out.

Question 10

1. Warmer air temperatures can make water evaporate more quickly than usual.
2. Water vapor rises upward and gradually gathers together to form clouds.
3. How fast water evaporates can increase when the surrounding temperature rises. (correct answer)
4. Condensation happens when cooling water vapor turns back into liquid droplets.

Explanation: The narration is the spoken part of the slideshow, and it is the only place that explains how temperature affects the process—so the detail that faster evaporation happens as the surrounding temperature rises must come from what you hear, not from what you read or see. The idea that warmer air makes water evaporate more quickly sounds close, but that is really the same temperature point reworded; the true audio detail is the one about how fast evaporation can change with rising temperature, and you should not pick a duplicate of it. The claim that water vapor rises and gathers into clouds describes the visual process you watch in the animation, not something added by the narration. The statement that condensation turns cooling vapor back into liquid droplets is a definition, and definitions in this slideshow come from the on-screen bullet-point text. To answer, you have to match each detail to the format—audio, visual, or text—that actually delivers it, instead of just repeating wording you saw in the question.
