One in every ten thousand males has the most common kind of hemophilia .It is extremely rare for females to have it. Patients can be treated with the missing clotting substance .They generally can lead normal lives. Scientists say gene treatment may be a possible way to cure hemophilia in the future .Researchers consider hemophilia the best disease for gene treatment because it is caused by a single fault gene .Also ,only a small increase in the missing clotting substance could provide good results .They tested gene treatment in six patients with severe hemophilia. First ,they removed skin cells from the patients' arms .The researchers grew the cells in the laboratory .They added copies of the needed gene taken from healthy people .Then they created hundreds of millions of genetically changed cells .They placed these cells into the patients' stomachs.After four months ,the amount of blood clotting substance in the blood increased in four of the six patients .Some of the patients reported a decrease in bleeding problems .However ,ten months later ,the clotting substance was no longer in the patients' blood .It is not clear if the implanted cells died or the added genes stopped working. The researchers say the study showed that gene treatment is safe for people with the most common kind of hemophilia .But others expressed concern about the treatment because the effects were only temporary. Options: A they are treated with the missing clotting substance B they accept scientists' help C good copies of gene are placed in their bodies D They place some genetically changed cells into their stomachs Answer: A they are treated with the missing clotting substance Question:

Stop line: There are stop lines in all crossing without traffic light (some have two stop lines and others have four stop lines). All cars must stop while meeting the stop line. 2. Traffic light: There is traffic light in the crossing of the road. Cars may almost turn every direction. The traffic light can give signal step by step including u-turn. There is a kind of middle lane of turning left. When a car wants to turn left in the road, he may enter into the middle lane of turning left and give a signal of turning left. When he thinks being safe, he may turn left. In many conditions the order of passing is also given very specifically. If people want to change lane or turn, they must look behind and think being safe. Only so, they may do it. 3.
