Reading the passage

These cosmologists explain our apparently lucky universe by proposing many universes. Most might not support life, but enough possibilities could give nature a good chance of getting a suitable set of laws at least once.

What we’re looking for

Think of the familiar typing-monkeys illustration. One monkey producing a line of Shakespeare by chance would be remarkable. Vast numbers of monkeys typing vast numbers of pages create far more opportunities for a match. That does not mean each monkey has become a better writer. The number of opportunities changes, not necessarily the chance of success on any individual attempt.

Working the answers

  • A

    The proposed universes coexist; we are not told that events in one affect another. The explanation does not require one universe to help or disrupt ours.

  • B

    This makes the very mistake the illustration warns against. More universes can improve the chance that at least one supports life without improving each universe's individual prospects. Adding a second opportunity is different from making the first opportunity better.

  • C

    The explanation depends on different possible arrangements of physical laws. Requiring the same laws everywhere would not supply those varied possibilities.

  • D
    Correct

    The third paragraph says the “sheer number of possibilities” gives nature a “good chance” to get the right laws at least once. D preserves both parts: many universes and a probable success somewhere among them. Neither the wording here nor the explanation requires a mathematical guarantee.

  • E

    At least one does not mean exactly one. The cosmologists' explanation works whether one universe or many universes contain life; no precise count is established.
