Which situation is most similar to the "positive feedback loop" (line 20)
described in passage 1?

a.
a professional tennis player wins a tournament,
which then qualifies him for additional tournaments.

b.
an online advertising firm sends advertisements to
an online customer, and the customer's choices
inform which advertisements are sent to her in the
future.

c.
a thermostat turns on the heat when the
temperature drops to a certain temperature, and
then turns off the heat when the temperature rises
to a certain temperature.

d.
a truck driver swerves to avoid a pothole. seeing
this, the driver of the car behind the truck avoids the
same pothole.

When a.  A professional tennis player wins a tournament,  which then qualifies him for additional tournaments, this is a "positive feedback loop."

A positive feedback loop refers to a situation where a change leads to a further change that would be incremental in nature.

The professional tennis player won a tournament which led to him qualifying for additional tournaments. The initial change was him winning a tournament and the incremental change was him being able to qualify for even more tournaments.

In conclusion therefore, winning a tournament that led to even more tournaments is a positive feedback loop.
