An example of these studies is one that was carried out by Susan Redline. She followed 240 teenagers in the USA and found that those who slept less than eight hours a night had on average 2.2% more fat in their daily food intake. So, if you want to keep your weight under control, I don't think you'll be staying up too late studying for your exams now.

Option 1: "It's common for teenagers to not get enough sleep. This can lead to weight gain."
Explanation: The text clearly states that many teenagers do not get the recommended nine hours of sleep, which is a common experience. It also directly connects insufficient sleep to increased consumption of high-fat and high-sugar foods, leading to weight gain. This option effectively captures the main idea of the text, which is the relationship between lack of sleep and weight gain among teenagers.
Option 2: "Teenagers often don't get enough sleep. This can cause lowered concentration and thus lower performance at school."
Explanation: While the option mentions that teenagers often don't get enough sleep, it incorrectly introduces the idea of lowered concentration and performance at school, which is not discussed in the text. The text focuses on the link between sleep deprivation and weight gain, not academic performance.
Option 3: "Some teenagers get less than eight hours sleep every night. However, they usually need nine hours."
Explanation: This option is partially correct in stating that some teenagers get less than eight hours of sleep and need nine. However, it fails to summarize the main consequence of this lack of sleep, which is the increase in weight due to higher fat and sugar consumption. Therefore, it does not capture the essence of the text.
Option 4: "Lack of sleep among teenagers leads to a dramatic increase in fat consumption and thus a significant weight gain."
Explanation: This option exaggerates the relationship by using the words 'dramatic' and 'significant,' which are not supported by the text. The text mentions an average increase of 2.2% in fat intake, which is not described as dramatic. Thus, this option misrepresents the information provided in the text.
