1) In curling, players use brooms to maneuver a giant stone to the center of a bull's-eye. Historically, the brooms were made from natural fibers, but that has changed in recent years. A broom made with artificial materials, dubbed the "Frankenbroom," gave players more control over the stone—too much control, according to fifty of the top curling teams. As a result of the controversy, Frankenbrooms were banned in 2015. However, other brooms have also raised concerns. For this reason, Canada's World Curling Federation (WCF) and the National Research Council of Canada (NRC) joined forces to measure how different brooms affect the stone and the ice. Match the cause "Frankenbrooms caused controversy" with an effect.... a) The WCF and NRC tested the brooms b) Officials banned the brooms 2) In curling, players use brooms to maneuver a giant stone to the center of a bull's-eye.

Match the cause "other brooms were questioned" with an effect.... a) The WCF and NRC tested the brooms b) The brooms maneuvered a giant stone 3) For years, fishermen in Bali used dynamite and cyanide to catch fish, which had the effect of destroying coral reefs in the area. In 2000, though, the Biorock reef restoration project began. Under normal conditions, a reef forms when polyps put down layers of calcium carbonate. In the Biorock process, a low electric current is sent through steel structures under ocean water, which causes calcium carbonate to form. Polyps attached to Biorock structures use the energy they would have spent building calcium carbonate and instead devote it to growing and fighting disease. The Biorock reefs therefore grow faster than regular reefs. What happened when "Fisherman used dynamite and cyanide".... a) coral reefs collapsed b) biorock reefs grow more rapidly 4)  What was the effect for when we learned that "biorock allows polyps to save energy" ... a) a low electric current b) biorock reefs grow more rapidly 5) Since 2013, the population of sea stars along North America's Pacific Coast has been dramatically reduced. Microbiologist Ian Hewson believes a type of virus known as Sea Star Association Densovirus (SSaDV) is responsible. Due to the disease, sea stars eventually decompose into a white sludge. Surprisingly, though, hundreds of sea star babies appeared in the spring of 2016 along the Oregon coast. Researchers think that the massive reduction in adult sea stars has contributed to the baby boom. Fewer hungry adult sea stars means more food for hungry babies. In turn, more food has led to a greater survival rate for the youngsters. What are two of the cause and effect scenarios from this reading? a) Sea stars are getting SSaDV so sea stars are disintegrating into white goo. b) Hundreds of seas star babies appeared so the survival rate is good c) Ian is a microbiologist, so he believes in viruses d) More food is available so more sea star babies are surviving
