Issue: 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." 第二題忘了^^" 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. -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.112.107.31
