The 10 sample cards as a list
  1. Choose: The new bell schedule had no noticeable (affect / effect) on how many students arrived late.
    effect

    After no noticeable and before on, the slot needs a noun meaning a result. Affect is the verb (to influence).
    Sound-Alikes
  2. Choose: The dark wooden benches make a handsome (complement / compliment) to the old stone fountain in the square.
    complement

    The benches go with the fountain and complete the look; nobody is praising anyone, so it's complement.
    Sound-Alikes
  3. Choose: My desk chair wobbles now because a screw under the seat came (loose / lose).
    loose

    A screw that is no longer tight has come loose. Lose is the verb for misplacing something or failing to win.
    Look-Alikes
  4. Choose: Underwater, a snorkel lets you (breath / breathe) while keeping your face in the water.
    breathe

    After lets you, the sentence needs a verb, and the verb is breathe. Breath is the noun, the air you take in.
    Look-Alikes
  5. Choose: From the coach's frown, the players could (imply / infer) that practice would run late.
    infer

    The players are drawing a conclusion from what they see, so they infer. The coach, who sends the hint, would be the one to imply.
    Near Meanings
  6. Choose: To settle the tie fairly, the club asked a (disinterested / uninterested) judge who knew none of the bakers.
    disinterested

    The club wants an impartial judge who gains nothing whoever wins: disinterested. An uninterested judge would simply not care, which wouldn't make the result fair.
    Near Meanings
  7. Choose: On hot afternoons, our dog likes to (lay / lie) in the shade under the porch.
    lie

    The dog is resting and isn't placing anything, so there's no object: lie. Lay needs an object (lay the leash down).
    Grammar Pairs
  8. Choose: Since the drought began, the creek carries far (fewer / less) water than it did last spring.
    less

    Water is measured, not counted one by one, so less. Fewer goes with plural things you count, like fewer fish.
    Grammar Pairs
  9. Choose: The city will (a lot / allot) each community garden member one small plot near the fence.
    allot

    After will, the sentence needs a verb, to give out shares: allot. A lot means many or much and isn't a verb.
    One Word or Two
  10. Choose: By the time Nia finished the math worksheet, the snow had (already / all ready) covered the whole driveway.
    already

    The snow covered the driveway before Nia finished, so already. Drop all from all ready and you get “the snow had ready covered,” which makes no sense.
    One Word or Two
