Q33:

When an active tooth in the shark’s jaws is lost or worn
down, many spare teeth lie in seemingly limitless reserve, each of which are
ready to slide into the appropriate position.

1. When an active tooth in the
        shark’s jaws is lost or worn down, many spare teeth lie in seemingly
        limitless reserve, each of which are ready to slide into the appropriate
        position.
2. Whenever an active tooth is
        lost or worn down, many spare teeth lie in seemingly limitless reserve in
        the shark’s jaws, which are each ready to slide into the appropriate
        position.
3. Many spare teeth lie in
        seemingly limitless reserve in the shark’s jaws, each one of which are
        ready to slide into the appropriate position when an active tooth is lost
        or worn down.
4. The many spare teeth lying in
        seemingly limitless reserve in the shark’s jaws, each one of which is
        ready to slide into the appropriate position whenever an active tooth is
        lost or worn down.

Q27:

Rye
sown in the fall and plowed into the soil in early spring leaves a residue that
is highly effective at controlling broad-leaved weeds, but unfortunately for
only about 45 days.  No major
agricultural crop matures from seed in as little as 45 days.  Synthetic herbicides, on the other hand,
although not any longer-lasting, can be reapplied as the crop grows.  Clearly, therefore, for major agricultural
crops, plowing rye into the soil can play no part in effective weed control.

The argument is most vulnerable to the objection that it
fails to

1. consider that there might be minor, quick-growing crops that do
        mature in 45 days or less
2. identify any alternative
        method of weed control that could be used instead of the method it rejects
3. distinguish among the various
        kinds of synthetic herbicides
4. allow for the possibility of
        combining the two weed-control methods it mentions
5. allow for the possibility
        that plants other than rye, handled the same way, might have the same
        effect
