The chemical symbol for water is H2O.

The sun revolves around the Earth.
False
True
In our solar system, the Earth and other planets orbit around the Sun due to its gravitational pull. The geocentric model was debunked in favor of the heliocentric model during the Renaissance.
A group of crows is called a murder.

True
A collective noun for a group of crows is indeed a 'murder.' This term dates back to the Late Middle Ages when fanciful names for animal groups became popular.

The Great Wall of China is visible from space with the naked eye.

Mercury is the closest planet to the Sun; Venus is the second closest. Mercury orbits at an average distance of about 58 million km, while Venus orbits at about 108 million km.
Gold is heavier than silver.
True
False
Gold has a density of about 19.3 g/cm³, which is much higher than silver's density of about 10.5 g/cm³. This makes gold significantly 'heavier' than silver by volume.
Albert Einstein won the Nobel Prize for his theory of relativity.

    Develop sharper discernment skills to distinguish factual information from myths or misconceptions in true and false trivia questions.

  3. Recall Surprising Facts -

    Strengthen memory retention by learning and remembering unexpected trivia tidbits presented throughout the quiz.

  4. Apply Quick Reasoning -

    Enhance your decision-making speed by applying logical reasoning under time pressure to answer true false trivia questions accurately.

  5. Evaluate Statement Reliability -

    Use your quiz score and feedback to measure progress and focus on areas needing improvement in true or false trivia mastering.

Cheat Sheet

  1. Verify with Reputable Sources -

    When approaching true or false trivia questions, cross-check statements against authoritative sites like Snopes.com or academic databases such as JSTOR. This two-source verification approach, endorsed by the Poynter Institute, helps reduce confirmation bias and ensures factual accuracy.

  2. Spot Qualifier Cues -

    In true false trivia questions, absolute words like "always," "never," or "all" often signal a likely falsehood, since most research findings allow exceptions (APA, 2020). For example, "All swans are white" ignores documented black swan populations in Australia (Monash University).

  3. Leverage Fact-Checking Tools -

    Use resources like Google Fact Check Explorer or "site:edu" and "site:gov" search filters to find original studies and official data quickly. According to a Harvard Library guide, targeted search operators can improve fact-checking efficiency by up to 30%.

  4. Build Domain Knowledge -

    Focus your review on key categories - history, science, geography, and pop culture - to confidently tackle any true or false trivia question. For instance, NASA's official site confirms that "Venus rotates faster than Earth" is false (NASA, 2021).

  5. Use Mnemonics and Memory Palaces -

    Enhance retention for facts and figures with mnemonic devices like "Every Good Boy Deserves Fudge" or the Method of Loci. Research from the University of Waterloo shows these techniques can boost recall performance by 20 - 50%.
