In sentence 1 a kayaker sinks their boat.  In sentence two no people are mentioned.  It is only stated a speedboat not a kayak.  The speedboat goes by but we do not know what the speedboat passes in contrast to sentence 1 where the kayaker sinks the boat.


Given the statement "One person kayaks as another kayer sinks their boat.", is the statement "A speedboat goes by" is true?
- Yes
- No
