    Got a hunch? Pick the answer that feels right.

    The answer, explained

    Six

    A hexagon is a six-sided polygon, from the Greek hex meaning six. Regular hexagons tile a flat surface perfectly, which is why honeybees build their comb cells in that shape.

    WORTH KNOWING

    A pentagon has five sides, a heptagon has seven and an octagon has eight, the shape used for stop signs.

    Which musical instrument has 88 keys in its standard modern form?

    Got a hunch? Pick the answer that feels right.

    The answer, explained

    Piano

    The standard modern piano has 88 keys, 52 white and 36 black, covering just over seven octaves from A0 to C8. The layout became the norm in the late nineteenth century.

    Got a hunch? Pick the answer that feels right.

    The answer, explained

    Five

    Which chess piece can only ever move diagonally?

    Got a hunch? Pick the answer that feels right.

    The answer, explained

    Bishop

    The bishop moves any number of squares diagonally, so each bishop stays on the colour of square it started on for the whole game. Rooks move in straight lines and queens combine both.

    Got a hunch? Pick the answer that feels right.

    The answer, explained

    A murder

    A group of crows is traditionally called a murder, a term that dates back to fifteenth-century English and probably reflects old superstitions about crows as omens of death.
