Adding Sound to Early Films

Film Studies · Medium · 1 min 22 sec · 5 questions

Transcript

Let's think about early cinema, back when films had no recorded soundtrack. We call them silent films, but the theaters were rarely silent. A live musician, often a pianist, sat below the screen and played along with the action, speeding up during a chase, slowing down for a sad scene. The music told the audience how to feel. When recorded sound finally arrived, it changed filmmaking in ways nobody expected. Here's the first surprise: early sound cameras were noisy, so they had to be sealed inside soundproof booths. That made the camera almost impossible to move, and for a while films actually became more static than they'd been in the silent era. It took engineers a few years to quiet the equipment and free the camera again. Now let me flag something about sound design specifically. Filmmakers realized that sound didn't have to be realistic — it had to be convincing. The footsteps you hear in a movie might be someone slapping gloves on a table; a punch might be a fist hitting a slab of meat. Sound artists build these effects deliberately, because a real recording often sounds thin and unconvincing. So the soundtrack you experience as natural is, in fact, carefully constructed — an illusion designed to feel real.

  1. 1. Why does the professor mention a fist hitting a slab of meat?

    • A.To describe how real punches are recorded on set
    • B.To argue that sound design is unnecessary
    • C.To explain why early cameras were noisy
    • D.To show that movie sound effects are deliberately constructed illusionsAnswer

    Why D (To show that movie sound effects are deliberately constructed illusions) is the answer: The example illustrates that effects 'didn't have to be realistic' but convincing, since real recordings sound thin.

    • A. It's a fabricated effect, not a recording of a real punch.
    • B. He argues sound design is essential, not unnecessary.
    • C. Camera noise is a separate earlier point.

  2. 2. What can be inferred about the soundtracks audiences perceive as natural?

    • A.They are usually raw recordings of real events
    • B.They are carefully built illusions designed to feel realAnswer
    • C.They are added only to comedy films
    • D.They are less effective than live piano music

    Why B (They are carefully built illusions designed to feel real) is the answer: He concludes the soundtrack 'you experience as natural is, in fact, carefully constructed — an illusion designed to feel real.'

    • A. Real recordings often sound thin, so effects are built instead.
    • C. Sound design applies broadly, not just to comedy.
    • D. No claim ranks constructed sound below live piano.

  3. 3. What is the lecture mainly about?

    • A.Why cameras stopped being used in cinema
    • B.How sound in film developed and how sound effects are constructedAnswer
    • C.Why silent films were more popular than sound films
    • D.How to become a theater pianist

    Why B (How sound in film developed and how sound effects are constructed) is the answer: The professor traces live music, the arrival of recorded sound, and the deliberate craft of sound effects.

    • A. Cameras kept being used; they were just temporarily restricted.
    • C. No popularity comparison is made.
    • D. The pianist is an example, not a how-to topic.

  4. 4. Why did films briefly become more static after recorded sound arrived?

    • A.Musicians refused to play faster music
    • B.Audiences preferred still images
    • C.Noisy cameras had to be sealed in soundproof boothsAnswer
    • D.The screens grew too large to film around

    Why C (Noisy cameras had to be sealed in soundproof booths) is the answer: He explains noisy sound cameras were 'sealed inside soundproof booths,' making them almost impossible to move.

    • A. Recorded sound replaced the live musician; their preferences aren't the cause.
    • B. Audience preference is not given as the cause.
    • D. Screen size is not mentioned as a factor.

  5. 5. What role did a live pianist play in silent-film theaters?

    • A.Recording dialogue for later playback
    • B.Playing music that told the audience how to feelAnswer
    • C.Selling tickets at the front of the theater
    • D.Operating the projector during screenings

    Why B (Playing music that told the audience how to feel) is the answer: He says the musician played along and 'the music told the audience how to feel.'

    • A. Silent films had no recorded dialogue for the pianist to record.
    • C. Selling tickets is not mentioned.
    • D. Operating the projector is not the pianist's role.

Banking the Seeds of Crop Diversity

Agricultural Science · Medium · 1 min 28 sec · 4 questions

Transcript

Imagine a vault, dug into a frozen mountainside, holding not gold but seeds, hundreds of thousands of varieties of the crops that feed us. That's a seed bank, and today I want to explain why such places matter more than they might first appear. Here's the problem they address. Modern farming tends to rely on a small number of high-yielding crop varieties. That's efficient, but it's also risky, because a single new disease or pest can sweep through fields that are all genetically similar. It's like relying on one key for every lock. If that key breaks, everything is stuck. Seed banks act as an insurance policy. They store the older, more diverse varieties, including wild relatives of our crops, which often carry traits like resistance to drought or disease that modern varieties have lost. When a threat appears, breeders can reach back into this stored diversity to find a plant with the trait they need. Now, storing seeds isn't as simple as putting them in a freezer and forgetting them. Seeds don't live forever. So, periodically, staff must plant samples, grow them, and harvest fresh seeds to renew the collection. It's ongoing, careful work. But the payoff is a living library that keeps our options open for a future we can't yet predict.

  1. 1. Why does the professor use the image of one key for every lock?

    • A.To describe how breeders unlock stored traits
    • B.To illustrate the danger of depending on similar cropsAnswer
    • C.To explain how seed vaults are locked and secured
    • D.To compare crops with metal tools

    Why B (To illustrate the danger of depending on similar crops) is the answer: The one-key analogy dramatizes the vulnerability of genetically uniform fields.

    • A. It illustrates risk, not the retrieval of traits.
    • C. It is a metaphor, not about physical locks.
    • D. The comparison is about vulnerability, not tools.

  2. 2. According to the professor, why is relying on a few crop varieties risky?

    • A.Wild relatives crowd out the modern crops
    • B.Breeders cannot access older varieties
    • C.The seeds cannot be frozen for storage
    • D.A single disease can sweep through genetically similar fieldsAnswer

    Why D (A single disease can sweep through genetically similar fields) is the answer: The professor says a single new disease or pest can sweep through fields that are all genetically similar.

    • A. Wild relatives are a stored resource, not a threat.
    • B. Seed banks exist precisely so breeders can access older varieties.
    • C. Freezing is part of storage, not the risk.

  3. 3. What can be inferred about maintaining a seed bank?

    • A.It requires ongoing effort to grow and renew the seedsAnswer
    • B.It eliminates the need for plant breeders
    • C.It is cheaper than using modern crop varieties
    • D.Once stored, seeds need no further attention

    Why A (It requires ongoing effort to grow and renew the seeds) is the answer: The professor stresses that seeds don't live forever, so staff must periodically grow and harvest fresh seeds.

    • B. Breeders use the bank; they are not replaced by it.
    • C. Cost comparison is not discussed.
    • D. The professor explicitly contradicts the freeze-and-forget idea.

  4. 4. What is the lecture mainly about?

    • A.How to build a vault inside a frozen mountain
    • B.Why seed banks are important for preserving crop diversityAnswer
    • C.How modern farming increased crop yields
    • D.Why freezers cannot store seeds at all

    Why B (Why seed banks are important for preserving crop diversity) is the answer: The professor explains why seed banks matter as insurance for crop diversity.

    • A. The vault image opens the talk but is not its subject.
    • C. High yields are noted as the risky context, not the topic.
    • D. Seeds are stored cold; the point is that they still need renewal.

These are Reach120 practice recordings written for the 2026 task format. None of them is a real TOEFL test item, and nothing on this page is published, licensed, endorsed or reviewed by ETS. Difficulty labels and durations are our own bank’s values.

What Listen to an Academic Talk asks you to do

  • A recorded talk on an academic subject, usually one instructor developing a single idea with examples.
  • Questions ask about the main idea, supporting detail, the function of a passage, and what the speaker implies.
  • Subject knowledge is never required — everything the questions need is in the recording.

What ETS states

  • The 2026 specification lists the Listening section at 47 items and 35 raw points, with task types Listen and Choose a Response, Listen to a Conversation, Listen to an Announcement, and Listen to an Academic Talk.

    These are published blueprint values, which the specification states are subject to minor revisions until the official launch. The item count includes non-scored items, so items do not equal raw points — the specification lists a maximum of 1 point per scored item.

  • The specification lists an estimated Listening time of an 18 minute router plus a second-stage module of 7 minutes (lower) or 11 minutes (upper).

    The times are estimated, and the two module lengths are discrete listed values — not a sliding 7-to-11-minute range.

  • Listening items are machine-scored selected responses, evaluated by rule-based algorithms per the specification’s item-type notes.

    Machine-scored is not exclusive to Reading and Listening — Build a Sentence is machine-scored too. This says nothing about how Reach120 scores your practice.

Sourced from the ETS 2026 test specifications, read (link confirmed ). Everything outside this box is Reach120’s own reading of it.

What the task actually measures

  • Whether you followed an argument across minutes rather than sentences.
  • Whether you can tell the claim from the example that illustrates it.
  • Whether you noticed the speaker signalling importance, contrast or a digression.

How this task type is scored

Every item on this task type is a selected response with one keyed answer, so a practice attempt is either right or wrong and there is no rubric to argue with. What the practice is worth is the reason a distractor pulled you — which is why every question below publishes why the key is right and why each wrong option looks right.

How to practice it without wasting the material

  1. 1Note the structure, not the sentences: claim, evidence, qualification, aside. Detail questions are easier to recover from a structure than from a wall of notes.
  2. 2Answer first, then read the transcript and find the sentence the key rests on.
  3. 3If you lose the thread halfway, note where. The recovery point is more useful information than the score on the item.

Listen to an Academic Talk: common questions

How long is a TOEFL academic talk?
ETS does not publish a per-recording length. Each Reach120 practice recording on this page prints its own duration, so the pacing figure you practice against is measured rather than assumed.
Do I need background knowledge in the subject?
No. The questions are answerable from the recording alone. A talk on seed banking or early film sound is testing listening, not the subject.
Is this the same as the old TOEFL lecture questions?
The 2026 specification names this task type Listen to an Academic Talk. The skill overlaps with pre-2026 lecture practice, but the section around it — adaptive, shorter, differently scored — does not.

Built against the TOEFL 2026 test specification, re-read on a 30-day cycle.
