Problem: Plants also detect the daily cycle of light and darkness. Do you know how plants respond to these changes? Some plants open their leaves during the day. It is during these hours the plant can collect sunlight. At night, the plant closes its leaves to prevent water loss. Many plants respond to the change in the length of the day. As days grow shorter, some plants respond by going dormant. Dormant is when a plant suspends its growth. It does this in order to survive. Shorter days signal the coming of winter. Winter in most areas means extreme cold. It is also very dry in the winter months. As winter approaches, some plants respond by their leaves changing color. After the change in color, they fall off. This dormancy period helps trees. It allows them to survive the cold and dry winter. Plants only want to grow when conditions are right.

Question: "Why do some plants go dormant in winter?"

Answer: "To survive the very wet winter conditions"
Answer: no

Problem: Moscow (CNN) -- Divers have completed their search of a Russian cruise ship that sank last weekend with the loss of many lives, the Emergency Situations Ministry told CNN Friday. The official death toll has reached 114 -- including 66 women, 28 children and 20 men, the ministry said. The bodies of 15 people are still missing. There were 208 people on the "Bulgaria" at the time of the accident Sunday, of whom 79 were rescued. Divers have checked all the boat's compartments, the ministry said, and are now looking for more bodies around the boat as well downstream on the Volga River, where they could have been carried by the current. The area where search efforts continue has been enlarged to 200 kilometers (125 miles) from the scene, Russian Transport Minister Igor Levitin said at a briefing Friday. Preparations are under way for the cruise ship to be raised from the river bottom in the coming days. Two large boat cranes, one from Moscow and another one from Volgograd, which will be used for the lifting, are on the way to the accident site. "We have asked the Emergency Situations Ministry to keep 23 divers at the scene to continue the search for bodies even during the lifting operation," Levitin said. Specialist military divers were brought in mid-week to aid in the search efforts. Four people face criminal charges over the sinking of the ship, which Russian media have called the most devastating river accident in the country's history.

Question: "Who was brought in to aid the search"

Answer: "Boat Cranes"
Answer: no

Problem: Our sun and other stars release light energy. At least this is what we see. Our Sun and stars also emit more than just light. Scientists call the type of energy that our Sun and stars release electromagnetic energy. This form of energy travels through space. Electromagnetic energy includes the light we see. It also includes much more. Many of these things we know about, but dont always think about. Electromagnetic energy includes radio waves, microwaves, and X rays. We now have devices in our homes and offices that release these same forms of energy. We use electromagnetic energy to make our lives better.

Question: "What is electromagnetic energy characterized as?"

Answer: "Light we see, radio waves, microwaves, and X rays"
Answer:
yes
