Problem: Given the question: You are given a new situation: Students learned about bread making in school, and were fascinated by the history of bread. They learned ancient bread making techniques that they experimented with later on.Group A experimented with Egyptian and Greek techniques, while group B made it the Croatian and the Turkish way. and a hint : The first evidence of baking occurred when humans took wild grass grains, soaked them in water, and mixed everything together, mashing it into a kind of slippery and wet broth-like paste.[3] The paste was cooked by pouring it onto a flat, hot rock, resulting in a bread-like substance. Later, when humans mastered fire, the paste was roasted on hot embers, which made bread-making easier, as it could now be made any time fire was created. The world's oldest oven was discovered in Croatia in 2014 dating back 6500 years ago. The Ancient Egyptians baked bread using yeast, which they had previously been using to brew beer.[4] Bread baking began in Ancient Greece around 600 BC, leading to the invention of enclosed ovens.[4] "Ovens and worktables have been discovered in archaeological digs from Turkey (Hacilar) to Palestine (Jericho) and date back to 5600 BC."[5] Please answer this question : Which people had a shorter bread baking history, Egyptian or Greek?
++++++++++++++++++++++++++++++++
The answer is:
Greek

Problem: Given the question: You are given a new situation: Two brothers went to the doctor's office for an appointment. The doctor discovered that Tim had very high levels of cholesterol, while Jim had normal levels. and a hint : Cholesterol has been implicated in heart disease for decades. Atherosclerosis is a disorder of the arteries in which cholesterol and other materials are deposited on the interior of the arterial wall. These deposits lead to the formation of plaques that can restrict or even block the flow of blood through these blood vessels (see Figure below ). A decrease in the flow of blood can lead to high blood pressure and a lowered oxygen supply to the heart muscle. A complete blockage of blood flow to parts of the heart (a heart attack) can cause significant damage due to oxygen deprivation, in some cases leading to death. Please answer this question : Which brother experiences a lowered oxygen supply to the heart muscle?
++++++++++++++++++++++++++++++++
The answer is:
Tim

Problem: Given the question: You are given a new situation: Dan is in his physics lab. He is experimenting with colliding particles. He has two samples of particles, sample A and sample B. Sample A contains gas particles, but sample B does not contain gas particles. and a hint : Another thing we can see in this animation is that particles are constantly colliding with one another. One assumption that we make when talking about collisions between gas particles is that they are completely elastic collisions. In an elastic collision , momentum is conserved, which means that none of the kinetic energy of the colliding particles is lost in some other form (such as the emission of light). This makes sense, because if energy were lost in collisions, the speeds of the particles would gradually decrease over time, and eventually everything would condense down into a solid form. Please answer this question : In which sample the momentum would not be conserved, sample A or sample B?
++++++++++++++++++++++++++++++++
The answer is:
sample B
