99"The purpose of many advertisements is to make consumers want to buy a
product so that they will 'be like' the person in the ad. This practice is
effective because it not only sells products but also helps people feel
better about themselves."

Argument:
37. Scientists studying historical weather patterns have discovered that in the
mid-sixth century, Earth suddenly became significantly cooler. Although few
historical records survive from that time, some accounts found both in Asia
and Europe mention a dimming of the sun and extremely cold temperatures.
Either a huge volcanic eruption or a large meteorite colliding with Earth
could have created a large dust cloud throughout Earth's atmosphere that
would have been capable of blocking enough sunlight to lower global
temperatures significantly. A large meteorite collision, however, would
probably create a sudden bright flash of light, and no extant historical
records of the time mention such a flash. Some surviving Asian historical
records of the time, however, mention a loud boom that would be consistent
with a volcanic eruption. Therefore, the cooling was probably caused by a
volcanic eruption.
