Explore what AI can do in daily life—and where popular claims go too far.

1. 1. 正しい答えを選んでください。

   You speak into your phone, and your words appear on the screen. What can AI speech recognition commonly do?

   • Turn spoken words into text, although mistakes can occur.
   • Recognize only sentences recorded during its training.
   • Capture every word correctly, even when speech is unclear.

   Consider both the useful ability and the effect of background noise.

   Show solution

   • Turn spoken words into text, although mistakes can occur.

   Speech recognition can handle new sentences, but noise, accents, and overlapping voices can affect accuracy.

2. 2. 正しい答えを選んでください。

   A streaming app recommends a show you enjoy. How does AI commonly produce recommendations like this?

   • It knows exactly what you are thinking at that moment.
   • It uses patterns in viewing behavior to predict your interests.
   • It relies entirely on interests you have explicitly listed.

   Your activity can provide clues even when you do not state your preferences.

   Show solution

   • It uses patterns in viewing behavior to predict your interests.

   Recommendations may use what you watch, skip, or rate, along with patterns from other viewers.

   You ask an image generator for a purple bicycle floating above a desert. What can this kind of AI do?

   • Find only an existing photograph that exactly matches the request.
   • Build every result by cutting complete objects out of stored photographs.
   • Generate a new image using visual patterns learned during training.

   Learning from images is not the same as searching for a finished picture.

   Show solution

   • Generate a new image using visual patterns learned during training.

   Image generators can combine familiar visual patterns in new ways; they are not simply photo-search tools.

   A travel review contains an idiom rather than a literal description. What can a modern AI translation system do with it?

   • Use context to translate its meaning, though it may still misunderstand.
   • Translate only the separate words, without using the surrounding sentence.
   • Always preserve every cultural meaning without needing to be checked by a person.

   Context helps, but it does not guarantee perfect understanding.

   Show solution

   • Use context to translate its meaning, though it may still misunderstand.

   Idioms often need a different expression in another language rather than a word-for-word translation.

5. 5. 正しい答えを選んでください。

   A chatbot confidently names a book and gives a quotation from it. What is true even if the answer sounds convincing?

   • Its confident wording guarantees that the book and quotation are real.
   • It may have invented the book or the quotation.
   • Giving a quotation means it has checked the original source.

   A natural-sounding answer and a verified answer are different things.

   Show solution

   • It may have invented the book or the quotation.

   AI can generate realistic-looking references that do not exist, so important sources need independent checking.

6. 6. 正しい答えを選んでください。

   A chatbot's training ended last month, and it has no access to live information. What can it reliably know about an event that happened yesterday?

   • The latest details, because every chatbot automatically receives news updates.
   • The exact outcome, because earlier patterns reveal later events with certainty.
   • Nothing, unless someone supplies current information.

   Consider where information about a new event would come from.

   Show solution

   • Nothing, unless someone supplies current information.

   Training knowledge is not a live news feed. Some systems gain current information through search tools or material users provide.

   A company trains a hiring AI on past decisions that unfairly favored one group. What can happen even if the software never explicitly mentions that group?

   • It may repeat unfair patterns through other details in the data.
   • It becomes fair automatically because computers have no personal opinions.
   • Removing the group's name guarantees that all unfair patterns disappear.

   Other details can be closely connected to group membership.

   Show solution

   • It may repeat unfair patterns through other details in the data.

   Details such as location can indirectly reflect group membership, allowing unfair patterns to survive.

   An AI system defeats a champion at chess. What does this achievement establish about its abilities?

   • It can handle unfamiliar everyday problems as well as the champion can.
   • It has exceptional skill at chess, not necessarily at unrelated tasks.
   • It can learn any human skill without further training or changes.

   A clear set of game rules is different from the variety of daily life.

   Show solution

   • It has exceptional skill at chess, not necessarily at unrelated tasks.

   Many AI systems are specialized: outstanding performance in one area does not automatically transfer to others.

9. 9. 正しい答えを選んでください。

   An AI tool has been properly tested for use in detecting signs of a particular disease in medical scans. What can it do in patient care?

   • Guarantee that every future case of the disease will be detected.
   • Remove the need for medical review whenever a scan result is uncertain.
   • Help clinicians spot suspicious patterns and make informed decisions.

   A useful medical tool can support a professional without being perfect.

   Show solution

   • Help clinicians spot suspicious patterns and make informed decisions.

   Clinicians can combine AI findings with symptoms, medical history, and other tests that a scan alone may not capture.

    A driverless taxi service operates in a mapped area but pauses during severe storms. What does this show about self-driving AI?

    • Its autonomous driving ability can be limited to certain places and conditions.
    • Mapping a road makes weather irrelevant to safe autonomous driving.
    • Success in one area guarantees safe operation on all public roads.

    Being autonomous does not mean being suitable for every environment.

    Show solution

    • Its autonomous driving ability can be limited to certain places and conditions.

    Weather can affect sensors and road conditions, even when the system already knows the route.

    An AI-text detector labels a student's essay "AI-written." What is true about this kind of result?

    • It proves that at least one sentence was generated by AI.
    • It is an estimate that can wrongly flag writing produced by a person.
    • It identifies the exact AI model that produced the essay.

    Patterns in wording do not provide a complete record of who wrote a text.

    Show solution

    • It is an estimate that can wrongly flag writing produced by a person.

    Human and AI writing can share features, so text detectors can produce both false accusations and missed detections.

    A chatbot says, "I feel lonely," and gives thoughtful replies. What is true about this behavior?

    • A believable description of loneliness confirms that it experiences that feeling.
    • Its use of the word "I" proves that it has a human-like sense of self.
    • Emotional language alone does not establish that it experiences feelings.

    Describing an experience and having that experience are not the same.

    Show solution

    • Emotional language alone does not establish that it experiences feelings.

    Training includes human conversations and stories, so chatbots can reproduce emotional expressions without this proving consciousness.
