Q: Two groups of children studied about some of the planets from our Solar system and their atmospheres. Group E studied about Earth, while group V studied about the planet Venus. Given the paragraph above, please answer correctly the following question: Which group studied less about clouds made of water vapor? Hint: Clouds on Earth are made of water vapor. Venus's clouds are a lot less pleasant. They are made of carbon dioxide, sulfur dioxide and large amounts of corrosive sulfuric acid! The atmosphere of Venus is so thick that the pressure on the surface of Venus is very high. In fact, it is 90 times greater than the pressure at Earth's surface! The thick atmosphere causes a strong greenhouse effect. As a result, Venus is the hottest planet. Even though it is farther from the Sun, Venus is much hotter even than Mercury. Temperatures at the surface reach 465C (860F). That's hot enough to melt lead!
A: group V

Q: Roger and Samantha are brother and sister. Both of them perform roughly the same amount of physical activity on a day-to-day basis. Roger, however, eats a lot more food relative to the amount he needs given his activity levels. Samantha, on the other hand, eats the appropriate amount of food given her level of activity. Given the paragraph above, please answer correctly the following question: Who is more likely to gain fat? Hint: Any unused energy in foodwhether it comes from carbohydrates, proteins, or lipidsis stored in the body as fat. An extra 3,500 Calories of energy results in the storage of almost half a kilogram (1 pound) of stored body fat. People who consistently consume more food energy then they need may become obese. Obesity occurs when the body mass index is 30.0 kg/m 2 or greater. Body mass index (BMI) is an estimate of the fat content of the body. It is calculated by dividing a person's weight (in kilograms) by the square of the person's height (in meters). Obesity increases the risk of health problems such as type 2 diabetes and hypertension.
A: Roger

Q: Mary and Ann are mother and daughter. Mary is in her 70's while Ann is in her late 40's. They both work out regularly for improved health. Mary has been experiencing some health issues lately. Given the paragraph above, please answer correctly the following question: Which person is at a greater risk of developing arthritis? Hint: During late adulthood, the risk of developing diseases such as cardiovascular diseases and cancer continues to rise. Most people also have a decline in strength and stamina. Their senses may start failing, and their reflex time typically increases. Their immune system also doesn't work as well as it used to. As a result, common diseases like the flu may become more serious and even lead to death. The majority of late adults develop arthritis, and as many as one in four develop Alzheimer's disease.
A: Mary

Q: Joe is at a party and carrying around a can of beer that he has had in his hand for awhile. He bumps into Sally, and they begin chatting. During their conversation, Sally notices the beer in Joe's hand, and remarks that a beer sounds like a good idea. She heads over to the refrigerator and grabs a nice cold one and pops it open. She takes a sip while the two continue their chat. Given the paragraph above, please answer correctly the following question: Is Sally's beer more or less dense than Joe's beer? Hint: Liquid water is a fluid. The hydrogen bonds in liquid water constantly break and reform as the water molecules tumble past one another. As water cools, its molecular motion slows and the molecules move gradually closer to one another. The density of any liquid increases as its temperature decreases. For most liquids, this continues as the liquid freezes and the solid state is denser than the liquid state. However, water behaves differently. It actually reaches its highest density at about 4C.
