Q: You are given a new situation: Two researches studied living organisms, Joe studied eukaryotes, while Bill studied prokaryotes. They were fascinated by genetic variation. and a hint : Prokaryotes have a different way to increase genetic variation. It's called genetic transfer or bacterial conjugation . It can occur in two ways. One way is when cells "grab" stray pieces of DNA from their environment. The other way is when cells directly exchange DNA (usually plasmids) with other cells. For example, as shown in Figure below , the donor cell makes a structure called an F pilus , or sex pilus. The F pilus attaches one cell to another cell. The membranes of the two cells merge and genetic material, usually a plasmid , moves into the recipient cell. Genetic transfer makes bacteria very useful in biotechnology. It can be used to create bacterial cells that carry new genes. Please answer this question : Which researcher observed more cells "grab" stray pieces of DNA from their environment?
A: Bill

Q: You are given a new situation: Mary was from a family that forbids all vaccinations. She never got any vaccines and developed immunity the hard way by getting many respiratory diseases. Ann got all here vaccines done in time and at the proper age. and a hint : Many respiratory diseases are caused by pathogens. A pathogen is an organism that causes disease in another organism. Certain bacteria, viruses, and fungi are pathogens of the respiratory system. The common cold and flu are caused by viruses. The influenza virus that causes the flu is pictured below ( Figure below ). Tuberculosis, whooping cough, and acute bronchitis are caused by bacteria. The pathogens that cause colds, flu, and TB can be passed from person to person by coughing, sneezing, and spitting. Illnesses caused by bacteria can be treated with antibiotics. Those caused by viruses cannot. Please answer this question : Which person experienced no tuberculosis?
A: Ann

Q: You are given a new situation: Two sister cities, located at different altitude, are affected differently by climate change. Bergen is at 60 degrees N, while Seattle is at 47 degrees N latitude. and a hint : During the Cold War, the Arctic became a place where the United States, Canada, and the Soviet Union performed significant research that has been essential to the study of climate change in recent years. A major reason why research in the Arctic is essential for the study of climate change is because the effects of climate change will be felt more quickly and more drastically in higher latitudes of the world as above average temperatures are predicted for Northwest Canada and Alaska. From an anthropological point of view, researchers study the native Inuit peoples of Alaska as they have become extremely accustomed to adapting to ecological and climate variability.[1] Please answer this question : Which city feels more drastic effects of climate change?
A: Bergen

Q: You are given a new situation: In ancient Greece King Juno asked two of his court philosophers, philosopher A and philosopher B, to come up with two interesting problems. Philosopher A devised a clever paradox and presented it before the court. He called the paradox Problem A. But philosopher B didn't come up with a paradox. He too presented a clever problem which was not a paradox - he called it problem B. and a hint : A paradox is a statement that, despite apparently valid reasoning from true premises, leads to an apparently-self-contradictory or logically unacceptable conclusion.[1][2] A paradox involves contradictory-yet-interrelated elements that exist simultaneously and persist over time.[3][4][5] Please answer this question : Which problem would more likely have logically unacceptable conclusion, problem A or problem B?
A:
problem A
