Question: (CNN) -- Four months after a criminal investigation began into the disappearance of an Oregon boy, officials continue to ask the public for leads and tips.

Thursday marks Kyron Horman's 8th birthday. Desiree Young, Kyron's biological mother, said she will celebrate the birthday by releasing red balloons outside a church in Medford, Oregon.

His stepmother, Terri Horman, said she dropped him off at Skyline Elementary School on the morning of June 4. She has been the subject of intense scrutiny for several months.

In divorce filings, her ex-husband, Kaine Horman, said he believes that Terri Horman "is involved" in the boy's disappearance.

Court documents also allege Terri Horman attempted to hire a man to kill her husband.

Meanwhile, Skyline Elementary began its first day of classes for the year on Tuesday with additional security measures to protect the children and staff.

In a letter to parents, Principal Ben Keefer said video cameras will be installed this weekend at Skyline.

"These cameras will show external views of the building as well as the main hallway," he wrote.

Also, security procedures will be reviewed to ensure they are effective, he added.

Tributes, messages, posters and cards that adorned a "Wall of Hope" for Kyron were moved from school property to a fence outside a nearby fire station, said the Multnomah County Sheriff's Office.

"We're happy that the fire district can provide this service to the community," said Tualatin Valley Fire & Rescue Communications Officer Brian Barker. "Our hearts go out to Kyron's family and we all hope for a positive resolution to this case." 1. Who was kidnapped?

Question: CHAPTER XXXVIII

From town to town, travelling for the most part on the platform of an engine, Maraton sped on his splendid mission. It was Ernshaw himself who drove, with the help of an assistant, but as they passed from place to place the veto was lifted. The men in some districts were a little querulous, but at Maraton's coming they were subdued. It was peace, a peace how splendid they were soon to know. By mid-day, trains laden with coal were rushing to several of the Channel ports. Maraton found his task with the miners more difficult, and yet in a way his triumph here was still more complete. He travelled down the backbone of England, preaching peace where war had reigned, promising great things in the name of the new Government. Although he had been absent barely forty-eight hours, it was a new London into which he travelled on his return. The streets were crowded once more with taxicabs, the evening papers were being sold, the shops were all open, the policemen were once more in the streets. Selingman, who had scarcely once left Maraton's side, gazed about him with wonder.

"It is a miracle, this," he declared. "There is no aftermath."

"The people are waiting," Maraton said. "We have given them serious pledges. Their day is to come."

"You believe that Foley will keep his word?" Selingman asked.

"I know that he will," Maraton replied. "As soon as the Bills are drafted, he will go to the country. It will be a new Party--the National Party. Stay and see it, Selingman--a new era in the politics of the world, a very wonderful era. The country is going to be governed for the people that are worth while." 1. who drove?

Question: Philosophers in antiquity used the concept of force in the study of stationary and moving objects and simple machines, but thinkers such as Aristotle and Archimedes retained fundamental errors in understanding force. In part this was due to an incomplete understanding of the sometimes non-obvious force of friction, and a consequently inadequate view of the nature of natural motion. A fundamental error was the belief that a force is required to maintain motion, even at a constant velocity. Most of the previous misunderstandings about motion and force were eventually corrected by Galileo Galilei and Sir Isaac Newton. With his mathematical insight, Sir Isaac Newton formulated laws of motion that were not improved-on for nearly three hundred years. By the early 20th century, Einstein developed a theory of relativity that correctly predicted the action of forces on objects with increasing momenta near the speed of light, and also provided insight into the forces produced by gravitation and inertia. 1. How long did it take for Newton's laws to be corrected?
2. Whose theory had accurate predictions? Provide a numbered list of answers.

Question: Three kids have been learning chemistry for only a few months. But they have already begun to challenge a world famous scientist! Li Weichi, Huang Runling, and Xiao Yan are from Zhongshan Huaqiao Middle School in Guangdong. They have just found a red cabbage that could be a new kind of acid-base indicator . They want it to take the place of litmus paper. "We've learnt to think of and ask questions about life by ourselves," said Li, "We work well with each other." British scientist Robert Boyle discovered the use of litmus paper over 300 years ago. Now it is used widely in experiments all over the world. But when the kids did some experiments in class last winter, they saw that the litmus paper didn't turn very blue with base matter. It's hard to get a clear result. Will there be a better indicator than litmus paper? The three kids decided to try and find out! How? They went to collect over 40 plants in parks, gardens and markets. Then they ground leaves, flowers and stems to get the pigments from them. The kids mixed pigments with acid and base. They spent months watching carefully to see which paper showed the best colour change. They decided it was the litmus paper! "It's our first scientific journey, Huang said, "But it makes me want to try harder." 1. What subject do the kids study?
2. How many kids are there?
3. What are their names?
