41-44題為題組 Dognition will help you learn more about your dog's cognitive traits. It offers an online test Is your dog an Einstein or a Charmer? For US $60, a recently-founded company called telling you about the brain behind the bark. Dognition's test measures a dog's intellect in several aspects-from empathy to memory to reasoning skills/ But don't expect it to measure your pet's IQ.) Dr. Hare, one of the venture's co- founders, says a dog's intelligence can't be described with a single number. Just as humans have a wide range of intelligences, so do dogs. The question is what type your dog relies on more. After you plunk your money down, Dognition's website will take you through a questionnaire about your dog: For example, how excited does your dog get around other dogs, or children? Do fireworks scare your pup? Then, Dognition guides you through tests that are as fun as playing fetch or hide-and-seek. At the end, you get a report of your dog's cognitive profile. Your dog could fall into one of nine categories: Ace, Stargazer, Maverick, Charmer, Socialite, Protodog, Einstein, Expert, or Renaissance Dog. That can give you something to brag about on Dognition's Facebook page. It also can shed new light on why dogs do the things they do. For example, a Charmer is a dog that trusts you so much that it would prefer to solve problems using information you give it rather than information it can get with its own eyes. Dognition helps people understand their dogs in ways that they have never been able to do. This new understanding can enrich the relationship between dogs and their owners. B 41 What is the third paragraph mainly about? (A) The theory behind the questionnaire used in the Dognition test. (B) The procedure for evaluating a dog's intellect on Dognition. D The products one can get by paying a fee to Dognition. (D) The characteristics of the activities Dognition offers. 又 42. According to the passage, which of the following statements is true? (A) Different dogs display strengths in different intelligences. BA dog's cognitive profile is composed of nine cognitive skills. The purpose of Dognition's testing is to control a dog's behavior. (D) A dog's intelligence can be ranked based on the score of a Dognition's test. K 43. Which of the following is closest in meaning to the word "venture" in the second paragraph (B) Risky attempt. (D) New business. (A) Creative measurement. 53% (C) Non-profit organization. 569 29 xyzcd.

想請問D的解釋

凡尼爾(C. B. van Niel,1897 ~ 1985)於1920 年代證實綠色細菌、紫硫菌與綠硫菌 在光照情形下,可將硫化氫(HS)氧化成硫(S)[式1〕。他也發現紫硫菌等細菌可氧 化某些有機化合物,以作為氫的提供者。與綠色植物光合作用的反應式〔式2〕相比之下, 凡尼爾推論光合作用所產生的 O, 來自水而非二氧化碳。魯賓(Ruben)等人於 1941 年用 同位素分別標定 C'°O, 與 HO 進行實驗,證實此推論為正確的。 200 (g),00 EX_2H,S + CO,→2S + (CH,O) + H, ....
