[Q]: Hank and Brian both grew up in the 1950s. They enjoyed playing with toys, but they each had a personal favorite. Hank's favorite toy as a child was his wooden baseball bat. Brian's favorite toy was a metal model car set that came with paint a child could use to paint the car however they wanted. They both have very fond memories of their childhood and Hank still has the baseball bat and his grandchildren now use it when they visit him. Given the paragraph above, please answer correctly the following question: Which child was less likely exposed to dangerous amounts of lead? Hint: Many chemicals that were once commonly used were later found out to be harmful to the environment , to human health, or both. The element lead was once a common additive to gasoline and to paint. Plumbing pipes were once typically made of lead. Only since the 1970s has the danger of lead become apparent. It causes brain damage and small children (who often chewed on objects painted with lead-based paint) are particularly susceptible. The use of lead in gasoline, paint, and plumbing pipes is now banned and new materials are being developed to replace the hazardous lead components.

input: Please answer the following: Greg is an environmental scientist. He wants to know how earth's atmosphere differed in two different time. To that end, he selected two time periods, time A and time B. Time A is set in the year one thousand when using fossil fuels was not very common. Time B is set in the year two thousand when fossil fuels are used in large quantities. Given the paragraph above, please answer correctly the following question: Would time B have more or less carbon dioxide released into the atmosphere than time A? Hint: When humans dig up and use fossil fuels, we have an impact on the carbon cycle ( Figure below ). This carbon is not recycled until it is used by humans. The burning of fossil fuels releases more carbon dioxide into the atmosphere than is used by photosynthesis. So, there is more carbon dioxide entering the atmosphere than is coming out of it. Carbon dioxide is known as a greenhouse gas , since it lets in light energy but does not let heat escape, much like the panes of a greenhouse. The increase of greenhouse gasses in the atmosphere is contributing to a global rise in Earth's temperature, known as global warming or global climate change.

Please answer this: Two researches studied adolescents during puberty. Tim studied males, while Dan studied females. Given the paragraph above, please answer correctly the following question: Which researcher didn't observe that the rate of growth usually starts to increase relatively early in puberty? Hint: Another obvious change that occurs during puberty is rapid growth. This is called the adolescent growth spurt . In boys, it is controlled by testosterone. The rate of growth usually starts to increase relatively early in puberty. At its peak rate, growth in height is about 10 centimeters (almost 4 inches) per year in the average male. Growth generally remains rapid for several years. Growth and development of muscles occur toward the end of the growth spurt in height. Muscles may continue to develop and gain strength after growth in height is finished.

Problem: Robert was watching the local news when he saw a report about a wildfire. The report stated that there was a brush fire in the southwest part of Texas, where it was currently daytime. When he switched the channel, he saw another report about a different wildfire. This one was a forest fire in the northwest part of Seattle, where it was currently nighttime. Given the paragraph above, please answer correctly the following question: Which area, Texas or Seattle, will have lower temperatures at the time of the fire? Hint: Wildfire intensity increases during daytime hours. For example, burn rates of smoldering logs are up to five times greater during the day because of lower humidity, increased temperatures, and increased wind speeds. Sunlight warms the ground during the day and causes air currents to travel uphill, and downhill during the night as the land cools. Wildfires are fanned by these winds and often follow the air currents over hills and through valleys. United States wildfire operations revolve around a 24-hour fire day that begins at 10:00 a.m. because of the predictable increase in intensity resulting from the daytime warmth.

A: Seattle
Problem: Given the question: Beth and Jane studied chemistry in school. However, Beth studied noble gasses while Jane decided to know more about alkanes. Given the paragraph above, please answer correctly the following question: Which student learned more about ethane? Hint: Saturated hydrocarbons are given the general name of alkanes . The name of specific alkanes always ends in - ane . The first part of the name indicates how many carbon atoms each molecule of the alkane has. The smallest alkane is methane. It has just one carbon atom. The next largest is ethane, with two carbon atoms. The chemical formulas and properties of methane, ethane, and several other alkanes are listed in Table below . The boiling and melting points of alkanes are determined mainly by the number of carbon atoms they have. Alkanes with more carbon atoms generally have higher boiling and melting points.

Problem: Frank and Noah were two researchers. Noah researched the climate of Antarctica, while Frank researched the climate changes of Madagascar and the Southern tip of Africa. Given the paragraph above, please answer correctly the following question: Which researcher didn't observe a particularly strong warming? Hint: Some of Antarctica has been warming up; particularly strong warming has been noted on the Antarctic Peninsula. A study by Eric Steig published in 2009 noted for the first time that the continent-wide average surface temperature trend of Antarctica is slightly positive at >0.05 C (0.09 F) per decade from 1957 to 2006. This study also noted that West Antarctica has warmed by more than 0.1 C (0.2 F) per decade in the last 50 years, and this warming is strongest in winter and spring. This is partly offset by autumn cooling in East Antarctica. There is evidence from one study that Antarctica is warming as a result of human carbon dioxide emissions, but this remains ambiguous. The amount of surface warming in West Antarctica, while large, has not led to appreciable melting at the surface, and is not directly affecting the West Antarctic Ice Sheet's contribution to sea level. Instead the recent increases in glacier outflow are believed to be due to an inflow of warm water from the deep ocean, just off the continental shelf. The net contribution to sea level from the Antarctic Peninsula is more likely to be a direct result of the much greater atmospheric warming there.In 2002 the Antarctic Peninsula's Larsen-B ice shelf collapsed. Between 28 February and 8 March 2008, about 570 km2 (220 sq mi) of ice from the Wilkins Ice Shelf on the southwest part of the peninsula collapsed, putting the remaining 15,000 km2 (5,800 sq mi) of the ice shelf at risk. The ice was being held back by a "thread" of ice about 6 km (4 mi) wide, prior to its collapse on 5 April 2009. According to NASA, the most widespread Antarctic surface melting of the past 30 years occurred in 2005, when an area of ice comparable in size to California briefly melted and refroze; this may have resulted from temperatures rising to as high as 5 C (41 F).A study published in Nature Geoscience in 2013 (online in December 2012) identified central West Antarctica as one of the fastest-warming regions on Earth. The researchers present a complete temperature...
