请阅读后面的三段文本，并综合本单元所学，判断那一段文本是以“专业的学术研究人员”为目标读者群体进行写作的，并用100-300字/词来陈述你的理由（中英文均可）。在阐述理由的时候，可以考虑从这几个方面去写：写作风格、专业词汇的使用、口语化表达、直接引用句子、以及文章写作的结构等纬度的判断理由，并且对三段文本进行了一定的比较分析。 文本1 （Text 1） Biologists from the University of Santiago in Chile have won an Ig Nobel award in 2015 for their research on how carnivore non-flying dinosaurs (meat-eating dinosaurs like the velociraptor and the T-Rex) moved. To do this, they dressed up a chicken with a kind of a stick in its backside. It’s true, it looks like a chicken with a plunger on its rear end, but the researchers think that its way of walking was "consistent with" how dinosaurs may have walked. In this way, they think they found how a two-legged non-flying dinosaur, such as a Tyrannosaurus Rex, might have gotten around. Dr. Grossi, the first author of this study, is highly enthusiastic about this prize, and he expects to keep answering “in an unorthodox way” to biomechanical questions of animals that lived millions of years ago. “This prize motivates me to keep doing non-traditional research”, he said. 文本2 （Text 2）In the work done by Grossi and his colleagues, they tried to replicate the locomotion of theropods using chickens. “The scientific evidence shows that theropod dinosaurs are direct ancestors of current birds, and even though they possess many similarities in their morphology, there are also differences, such as the presence of a fleshy, heavy tail in those dinosaurs, which is absent in birds, and the increase in the size of birds’ arms in order to develop active flight. These morphologic changes also generate changes in the mass center of these animals and therefore should affect the way dinosaurs walked. Using recently hatched chickens, from day one we put them an artificial tail attached to their backs with a t-shirt, simulating a primitive theropod tail. The results on the way adult chickens with artificial tails moved their rear limbs during walking, give us important clues about how they dinosaur ancestors moved”, says Dr. Grossi. 文本3 （Text 3） Birds still share many traits with their dinosaur ancestors, making them the best living group to reconstruct certain aspects of non-avian theropod biology. Bipedal, digitigrade locomotion and parasagittal hindlimb movement are some of those inherited traits. Living birds, however, maintain an unusually crouched hindlimb posture and locomotion powered by knee flexion, in contrast to the inferred primitive condition of non-avian theropods: more upright posture and limb movement powered by femur retraction. Such functional differences, which are associated with a gradual, anterior shift of the centre of mass in theropods along the bird line, make the use of extant birds to study non-avian theropod locomotion problematic. Here we show that, by experimentally manipulating the location of the centre of mass in living birds, it is possible to recreate limb posture and kinematics inferred for extinct bipedal dinosaurs. Chickens raised wearing artificial tails, and consequently with more posteriorly located centre of mass, showed a more vertical orientation of the femur during standing and increased femoral displacement during locomotion. Our results support the hypothesis that gradual changes in the location of the centre of mass resulted in more crouched hindlimb postures and a shift from hip-driven to knee-driven limb movements through theropod evolution. This study suggests that, through careful experimental manipulations during the growth phase of ontogeny, extant birds can potentially be used to gain important insights into previously unexplored aspects of bipedal non-avian theropod locomotion. 用下面的结构进行回答： 判断：文本"?"是以“专业的学术研究人员”为目标读者群体进行写作的 理由：我作出上述判断的理由是（100-300字/词）：1）～～2）～～3）～～
