Pls Help me Read the introduction from an argumentative essay
about national parks.
Most people who visit national parks are likely focused
on the experience of visiting natural wonders. However,
they may not realize how much time, money, and effort
are necessary to maintain these parks. National parks
must be preserved.

How could the writer strengthen the claim in this
introduction?

O by focusing on different national parks
O by adding supporting evidence
O by adding a topic sentence
by focusing on a counterargument
