the greenhouse effect traps heat near earth's surface. greenhouse gases in the atmosphere—carbon dioxide, water vapor, methane, and nitrous oxide—allow the shorter waves of ultraviolet radiation from the sun to enter earth's lower atmosphere. however, these gases do not allow the longer wavelengths of infrared radiation to pass back out to the outer atmosphere. the result is that the lower atmosphere heats up. this result happens naturally, but it can be accelerated by human activities. since the late 1800s, human activity has greatly altered the amount of greenhouse gases that enter the atmosphere. burning fossil fuels, farming, and clearing forests, as well as industry, have all contributed to increases of carbon dioxide (co2), methane, nitrous oxide, and other greenhouse gases in the atmosphere. the result is that temperatures in the troposphere have gone up. many scientists identify this increase in greenhouse gas emissions as contributing directly to global warming. this suggests that human activity has had an impact on the global climate.
the author argues that in modern times, the greenhouse effect *
a- keep the earth warm
b-has increased because of human activity
c-is in a natural cycle of changing
d-has changed local weather patterns

Martha has a deck of cards. she has lost some of the cards, and now the deck only contains nine spades, eleven diamonds, eight clubs, and twelve hearts. martha predicts that whenever she draws a card from the deck without looking, she will draw a club one-fifth of the time. which activity would best allow martha to test her prediction? a. randomly draw a card from the box and see if it is a club. b. randomly draw a card. then, continue to draw another card until all eight clubs are drawn. c. randomly draw and replace a card 120 times. then, observe how close to 30 times a club is drawn. d. randomly draw and replace a card 100 times. then, observe how close to 20 times a club is drawn.
