※ 引述《lovekyoko (匹茲堡的天空)》之銘言： : 24-35: The milk of many mammals contains cannabinoids, substances that are : known to stimulate certain receptors in the brain. To investigate the : function of cannabinoids, researchers injected newborn mice with a chemical : that is known to block cannabinoides from reaching their receptors in the : brain. The injected mice showed far less interest in feeding than normal : newborn mice do. Therefore, cannabinoids probably function to stimulate the : appetite. : Which of the following is an assumption ok which the argument depends? : A)Newborn mice do not normally ingest any substance other than their mothers’ : milk. : B)Cannabinoids are the only substances in mammals’ milk that stimulate the : appetite. : C)The mothers of newborn mice do not normally make any effort to encourage : their babies to feed. : D)The mild of mammals would be less nutritious if it did not contain : cannabinoids. : E)The chemical that blocks cannabinoids from stimulating their brain : receptors does not independently inhibit the appetite. : 我被B跟E給迷惑了 : B取非還有其他的物質可以刺激食慾 : E取非這化學物質可以獨立的抑制食欲 : 請問BE取非有反駁節論嗎我覺得都沒有耶 : 答案是E : 謝 E取非有反駁結論 E取非的意思代表的是食慾被抑制不是因為cannabinoids被block 而是因為這個後來注射的化學物質本身就會抑制食慾使得食慾跟cannabinoids之間的關連被打斷因此會反駁cannabinoids有刺激食慾效用的結論 B取非則沒有辦法明確的反駁。「可能有其他物質能刺激食慾」這句話代表的是可能後來注射的化學物質block的是那一些其他物質使得食慾下降但是在這邊仍然無法明確的知道究竟cannabinoids有沒有刺激食慾的功用 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 61.216.0.208
