input question: I read this background article the other day: Ecology is the study of ecosystems. An ecosystem consists of all the living and nonliving components of the habitat. Whereas nutrients and certain elements are recycled through ecosystems, energy moves in just one direction. Many interactions among species within an ecosystem are centered around the flow of energy. The formation of ecosystems, from new land to current habitats, is usually based on the pioneer species, and these species are able to live in an area due to the nonliving factors, such as the climate, the soil and the amount of rainfall, of that area. The populations within an ecosystem also determine the stability of the system. Recent tremendous increases in the human population have raised many important ecological issues. I am facing a new situation today: Two brothers liked natural sciences. Ben decided to study Ecology, while his brother Dan decided to study Geography. They studied a lot and became very good at these subjects. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which brother studied more nonliving components of the habitat????
output answer: Ben

input question: I read this background article the other day: Noble gases are also used to fill the glass tubes of lighted signs like the one in the Figure below . Although noble gases are chemically nonreactive, their electrons can be energized by sending an electric current through them. When this happens, the electrons jump to a higher energy level. When the electrons return to their original energy level, they give off energy as light. Different noble gases give off light of different colors. Neon gives off reddish-orange light, like the word "Open" in the sign below. Krypton gives off violet light and xenon gives off blue light. I am facing a new situation today: A scientist named Kathy walks into her office to see two neon signs plugged into the wall and hanging above her desk. Confused, she looks around to see if there's any clue as to who put them there. Seeing nobody, she flips the light switch on and walks in. Upon flipping the light switch, only the large sign lights up. Even though they are clearly both plugged in, the small sign isn't turning on. Kathy leaves her office to find someone to ask who put these random signs up in her room. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which sign's electrons are at a higher energy level????
output answer: large sign

input question: I read this background article the other day: While the Grants were on the Galapagos, a drought occurred. As a result, fewer seeds were available for finches to eat. Birds with smaller beaks could crack open and eat only the smaller seeds. Birds with bigger beaks could crack and eat seeds of all sizes. As a result, many of the small-beaked birds died in the drought. Birds with bigger beaks survived and reproduced (see Figure below ). Within 2 years, the average beak size in the finch population increased. Evolution by natural selection had occurred. I am facing a new situation today: The explorers visited Galapagos 1 and Galapagos 2, both islands part of the same archipelago. Island 1 had experienced a drought in recent years. Both islands had populations of birds living there. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which island had fewer small-beaked birds that could only crack open smaller seeds????
output answer: Galapagos 2

input question: I read this background article the other day: Sand mining is a direct cause of erosion, and impacts the local wildlife.[2] Various animals depend on sandy beaches for nesting clutches, and mining has led to the near extinction of gharials (a species of crocodile) in India. Disturbance of underwater and coastal sand causes turbidity in the water, which is harmful for organisms like coral that need sunlight. It can also destroy fisheries, financially harming their operators. Removal of physical coastal barriers, such as dunes, sometimes leads to flooding of beachside communities, and the destruction of picturesque beaches causes tourism to dissipate. Sand mining is regulated by law in many places, but is often done illegally.[3] Globally, it is a $70 billion industry, with sand selling at up to $90 per cubic yard.[4] I am facing a new situation today: Sand mining in the north coastal region was stopped 20 years ago, but it still continues to this day in the south region. Both fishing communities there are still prosperous, but the southern one had a couple of bad years, with fish and other marine wildlife becoming more scarce. The southern beach had erosion problems as well. The northern beach recovered, and is suitable for tourism. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which region is less suitable for tourism????
output answer:
southern
