David is a martial arts enthusiast, watching every martial arts movie he can find. This year David and his friend John is visiting the Fujian Province to see the martial arts competition. There are two rounds of competition, round A and round B. Round A competitors would display southern Chinese martial arts while round B competitors would display northern Chinese martial arts. and a hint : Some Chinese martial arts instructors focus more on their qinna techniques than others.

The southern Chinese martial arts have more developed qinna techniques than northern Chinese martial systems. The southern martial arts have much more prevalent reliance on hand techniques which causes the practitioner to be in closer range to their opponent. There are over 700 qinna traditional techniques found in all martial arts. In the Non-Temple White Crane style there are 150-200 qinna techniques alone. Along with Fujian White Crane, styles such as Northern Eagle Claw (Ying Jow Pai) and Tiger Claw (Fu Jow Pai) have qinna as their martial focus and tend to rely on these advanced techniques.

You are given a new situation: Two groups of athletes were part of an experiment. Group One ran 10 miles without charging up their body with glycogen at the start of the exercise, and didn't eat or drink other supplements during the race. Group Two did everything by the book and had better overall results. and a hint : In endurance sports such as cycling and running, hitting the wall or the bonk is a condition of sudden fatigue and loss of energy which is caused by the depletion of glycogen stores in the liver and muscles.

The condition can usually be avoided by ensuring that glycogen levels are high when the exercise begins, maintaining glucose levels during exercise by eating or drinking carbohydrate-rich substances, or by reducing exercise intensity. Please answer this question : Which group had more runners experiencing sudden fatigue?
Ans: One

You are given a new situation: A large amount of radioactive waste was found near the town of Arrester. An unusual number of people in Arrester have cancer. In a town 100 miles north of Arrester named Ajani very few people have cancer. There is no radioactive waste near the town of Ajani and a hint : Cancer is a disease that causes cells to divide out of control. Normally, the body has systems that prevent cells from dividing out of control. But in the case of cancer, these systems fail. Cancer is usually caused by mutations. Mutations are random errors in genes. Mutations that lead to cancer usually happen to genes that control the cell cycle. Because of the mutations, abnormal cells divide uncontrollably. This often leads to the development of a tumor. A tumor is a mass of abnormal tissue. As a tumor grows, it may harm normal tissues around it. Anything that can cause cancer is called a carcinogen . Carcinogens may be pathogens, chemicals, or radiation. Please answer this question : Will a person moving to Arrester have an increased or decreased chance of developing cancer?
