[Q]: China used alternative fuels to generate electricity, while Mongolia burned lots of fossil fuels. There were frequent debates between the two countries on this matter. Given the paragraph above, please answer correctly the following question: Which country released less carbon dioxide into the atmosphere? Hint: Carbon dioxide is the most significant long-lived greenhouse gas in Earth's atmosphere. Since the Industrial Revolution anthropogenic emissions primarily from use of fossil fuels and deforestation have rapidly increased its concentration in the atmosphere, leading to global warming. Carbon dioxide also causes ocean acidification because it dissolves in water to form carbonic acid.

input: Please answer the following: Guyana and Nigeria had thriving economies. Guyana's economy was based on conventional agriculture, while Nigeria attracted an enormous number of tourists to its splendid beaches each year. Given the paragraph above, please answer correctly the following question: Which country caused more marine debris? Hint: Marine pollution is a generic term for the entry into the ocean of potentially hazardous chemicals or particles. The biggest culprits are rivers and with them many agriculture fertilizer chemicals as well as livestock and human waste. The excess of oxygen-depleting chemicals leads to hypoxia and the creation of a dead zone.Marine debris, which is also known as marine litter, describes human-created waste floating in a body of water. Oceanic debris tends to accumulate at the center of gyres and coastlines, frequently washing aground where it is known as beach litter.

Please answer this: The fruit harvest was awesome this year, so Mary decided to experiment by candying some raspberries, apricots and apples. She didn't candy plums, raspberries and pears though. the candied fruit lasted longer, preserved their aroma and tasted delicious. Given the paragraph above, please answer correctly the following question: Which of Mary's fruit are saturated with sugar, apples or plums? Hint: Candied fruit, also known as crystallized fruit or glace fruit, has existed since the 14th century. Whole fruit, smaller pieces of fruit, or pieces of peel, are placed in heated sugar syrup, which absorbs the moisture from within the fruit and eventually preserves it. Depending on size and type of fruit, this process of preservation can take from several days to several months.[1] This process allows the fruit to retain its quality for a year.[2] The continual process of drenching the fruit in syrup causes the fruit to become saturated with sugar, preventing the growth of spoilage microorganisms due to the unfavourable osmotic pressure this creates.[3]

Answer: apples
Problem: David is a chemical engineer. Yesterday, he was working on two samples, sample A and sample B. Sample A was a strong acid, and sample B was a weak acid. David needed to find the differences between them. Given the paragraph above, please answer correctly the following question: Which would partially ionize in water, sample A or sample B? Hint: The strength of an acid refers to its ability or tendency to lose a proton. A strong acid is one that completely dissociates in water; in other words, one mole of a strong acid HA dissolves in water yielding one mole of H+ and one mole of the conjugate base, A, and none of the protonated acid HA. In contrast, a weak acid only partially dissociates and at equilibrium both the acid and the conjugate base are in solution. Examples of strong acids are hydrochloric acid (HCl), hydroiodic acid (HI), hydrobromic acid (HBr), perchloric acid (HClO4), nitric acid (HNO3) and sulfuric acid (H2SO4). In water each of these essentially ionizes 100%. The stronger an acid is, the more easily it loses a proton, H+. Two key factors that contribute to the ease of deprotonation are the polarity of the HA bond and the size of atom A, which determines the strength of the HA bond. Acid strengths are also often discussed in terms of the stability of the conjugate base.

A: sample B
Problem: Given the question: Usain was once a competitive swimmer, but he became bored with the sport and decided to start running very frequently instead. Usain tried to convince his brother, Asafa, to take up running as well. Asafa didn't really like running, though, so he hardly ran much at all. Given the paragraph above, please answer correctly the following question: Who will increase the strength of their cardiac muscles less? Hint: In exercises such as weight lifting, skeletal muscle contracts against a resisting force (see Figure below ). Using skeletal muscle in this way increases its size and strength. In exercises such as running, the cardiac muscle contracts faster and the heart pumps more blood. Using cardiac muscle in this way increases its strength and efficiency. Continued exercise is necessary to maintain bigger, stronger muscles. If you don't use a muscle, it will get smaller and weakerso use it or lose it.

The answer is:
Asafa
Problem: Different wavelength electromagnetic radiations have different uses. John is a physicist. He needed to find appropriate wavelength electromagnetic radiations for his experiments. To that end, he selected three electromagnetic radiations, microwaves, infrared light, and visible light. He noted microwaves as case A, infrared as case B, and visible light as case C. Given the paragraph above, please answer correctly the following question: Would case B have longer or shorter wavelengths than case A? Hint: Infrared (IR) light is electromagnetic radiation with a wavelength between 0.7 and 300 micrometers, which corresponds to a frequency range between 430 and 1 THz respectively. IR wavelengths are longer than that of visible light, but shorter than that of microwaves. Infrared may be detected at a distance from the radiating objects by "feel." Infrared sensing snakes can detect and focus infrared by use of a pinhole lens in their heads, called "pits". Bright sunlight provides an irradiance of just over 1 kilowatt per square meter at sea level. Of this energy, 53% is infrared radiation, 44% is visible light, and 3% is ultraviolet radiation.
