Question: Q: You are given a new situation: Two neighboring dairy farms produced milk for half the state.  Berry farm produced conventional milk, while Rose farm produced organic milk.  and a hint : Compared to conventional milk production, organic milk production tends to have lower eutrophication potential per ton of milk or per hectare of farmland, because it potentially reduces leaching of nitrates (NO3−) and phosphates (PO4−) due to lower fertilizer application rates. Because organic milk production reduces pesticides utilization, it increases land use per ton of milk due to decreased crop yields per hectare. Mainly due to the lower level of concentrates given to cows in organic herds, organic dairy farms generally produce less milk per cow than conventional dairy farms. Because of the increased use of roughage and the, on-average, lower milk production level per cow, some research has connected organic milk production with increases in the emission of methane.Animal welfare issues vary among dairy farms and are not necessarily related to the way of producing milk (organically or conventionally).  Please answer this question : Which farm had production with higher eutrophication potential per ton of milk or per hectare of farmland?
A: Berry

Q: You are given a new situation: David is a physician with the children's hospital. He is seeing four patients, patient A, patient B, patient C, and patient D. Patient A is a male with Klinefelter's syndrome. Patient B is female with Turner syndrome. Patient C is a male and does not have any of these illnesses. Patient D is a female and she too does not have any of these illnesses.  and a hint : Klinefelter's syndrome is caused by the presence of one or more extra copies of the X chromosome in a male's cells. Extra genetic material from the X chromosome interferes with male sexual development, preventing the testicles from functioning normally and reducing the levels of testosterone. Triple X syndrome (trisomy X) results from an extra copy of the X chromosome in each of a female's cells. Females with trisomy X have a lower IQ than their siblings. Turner syndrome results when each of a female's cells has one normal X chromosome and the other sex chromosome is missing or altered. The missing genetic material affects development and causes the characteristic features of the condition, including short stature and infertility.  Please answer this question : Which patient would not have extra copies of X chromosome, patient A or patient B?
A: patient B

Q: You are given a new situation: John wanted to do a thought experiment. To that end, he started his journey under the full moonlight on Earth. He labeled that as time A. Then he entered his living room. He labeled that as time B. Next he traveled to Saturn. He labeled that as time C. After that, he traveled to Pluto. He labeled that as time D. Then he went to 90377 Sedna. He labeled that as time E. At the end, he returned back to Earth at sunset. He labeled that as time F.  and a hint : For comparison,  sunlight on Saturn is slightly brighter than Earth sunlight at the average sunset or sunrise (see daylight for comparison table). Even on Pluto, the sunlight would still be bright enough to almost match the average living room. To see sunlight as dim as full moonlight on Earth, a distance of about 500 AU (~69 light-hours) is needed; there are only a handful of objects in the Solar System known to orbit farther than such a distance, among them 90377 Sedna and (87269) 2000 OO67.  Please answer this question : Would time C be brighter or dimmer than time F?
A: brighter

Q: You are given a new situation: Albert is a scientist who travels the planet looking for new species to discover and analyze. While on a safari in Australia, Albert discovered two new species of live-bearing tetrapods. In the first species, species C, the females had long gestational periods. In the second species, species D, the females had short gestational periods.  and a hint : From the data he collected and documented, Aristotle inferred quite a number of rules relating the life-history features of the live-bearing tetrapods (terrestrial placental mammals) that he studied. Among these correct predictions are the following. Brood size decreases with (adult) body mass, so that an elephant has fewer young (usually just one) per brood than a mouse. Lifespan increases with gestation period, and also with body mass, so that elephants live longer than mice, have a longer period of gestation, and are heavier. As a final example, fecundity decreases with lifespan, so long-lived kinds like elephants have fewer young in total than short-lived kinds like mice.  Please answer this question : Which species will have shorter living individuals?
A:
Answer: species D
