The 6 sample questions as a list
  1. To fight rising childhood ______, the city opened free after-school sports leagues and put drinking fountains in every park in place of soda machines.

    A) dehydration
    B) metabolism
    C) obesity
    D) inflammation
    C) obesity

    More exercise and fewer sugary drinks target excess body fat, so the city is fighting obesity. Dehydration is tempting because of the fountains, but soda quenches thirst too; trading it for water cuts sugar, not a shortage of body water.
    Body & Health
  2. Because the measles ______ teaches the body to recognize the virus in advance, a child who gets both doses is very unlikely ever to catch the disease.

    A) antibody
    B) vaccine
    C) antibiotic
    D) transfusion
    B) vaccine

    A dose that teaches the immune system ahead of infection is a vaccine. Antibody is tempting, but antibodies are what the body makes in response; they don't come in doses that teach it anything.
    Disease & Infection
  3. Rather than survey hundreds of schools, the researcher published a detailed ______ of one rural school that had cut its absences in half.

    A) meta-analysis
    B) peer review
    C) case study
    D) proof of concept
    C) case study

    Research that draws wider lessons from a close look at one place is a case study. Meta-analysis is tempting as another kind of study, but it combines many earlier studies, and this one looks at a single school.
    Research & Technology
  4. Now that scientists have mapped the axolotl's complete ______, they hope to find the genes that let this salamander regrow a lost leg.

    A) chromosome
    B) anatomy
    C) microbiome
    D) genome
    D) genome

    Everything in an animal's DNA, its genes included, is its genome. Chromosome is tempting because chromosomes carry genes, but an axolotl has many chromosomes, so one is not its complete genetic material.
    Genes & Life
  5. Nitrogen makes up most of the air yet traps almost no heat, while carbon dioxide, only a tiny fraction of it, is one ______ that warms the planet.

    A) greenhouse gas
    B) fossil fuel
    C) ozone layer
    D) carbon footprint
    A) greenhouse gas

    A gas that soaks up heat rising off Earth is a greenhouse gas. Fossil fuel is tempting because burning one releases carbon dioxide, but a fossil fuel is the coal, oil or gas burned, not the gas left after.
    Earth & Climate
  6. Saturn's largest ______, Titan, is wider than the planet Mercury and is the only moon known to have a thick atmosphere.

    A) asteroid
    B) satellite
    C) exoplanet
    D) nebula
    B) satellite

    A moon that a planet keeps in orbit is a natural satellite. Asteroid is tempting because both are solid bodies, but an asteroid orbits the sun, while Titan orbits Saturn.
    Space
