( Based on the growth rates of large modern reptiles such as ) the Galapagos tortoise and examination of fossils of juvenile dinosaurs, scientists estimate that the larger dinosaurs probably lived to be between 100 and 200 years old. A. Based on the growth rates of large modern reptiles such as B. On the basis of growth rates of large modern reptiles such as C. Based on the growth rates of large modern reptiles like D. On the basis of growth rates of large modern reptiles, like those of E. Based on the growth rates as those of large modern reptiles like 答案是B，错选了A。科学家基于爬行动物的生长率，估计了恐龙的存活时间。科学家做based on的逻辑主语有错吗？麻烦老师讲解。 (Based on account of various ancient writers) , scholars have painted a sketchy picture of the activities of an all-female cult that, perhaps as early as the sixth century B.C, worshipped a godness known in Latin as Bona Dea "the good goddess". A. Based on account of various ancient writers B. Basing it on various ancient writer's accounts C. With accounts of various ancient writers used for a basis D. By the accounts of various ancient writers they used E. Using accounts of various ancient writers 答案是E，还是错选了A。做题时在AE纠结了好久，因为不确定学者作为“基于不同作家的解释”的主语是不是错的，而且感觉基于要比使用的表达更好，尽管可以确定using的主语是学者，但还是把E排除了，麻烦老师讲解。 因为不知道这两道题是犯了什么错误，所以去有道查了based on 的例句，发现人是可以做主语的：Based on the finding, one might predict that the bank should increase its display and budget. 以及 Based on that representation, the district judge denied a motion to dismiss the new comlaint. 麻烦老师讲解这几个题的区别。

请问下金老师，先通过主谓一致排除a，通过in doing sth “在哪方面干什么”意思不对排除ce，剩下bd怎么选择呢？感觉时态没法做选择，前面一个用using 一个用by the use of …使用过动词优于名词来最后选择b吗？

想请问Tina老师，这个题通过后面画线部分比较选项可以排出ad，cwith结构修饰主句主谓关系不恰当排除c，同位语be中summarize前面那群borrowers更好，但是be比较，我觉得e更好，因为that感觉又是引导一个如records这个名词的同位语解释说明什么样的一个热cords，但是答案选b，该怎么权衡呢？

请老师完整解答一下这道题解题思路，我选的A，认为后面是一个介词短语修饰语。

王文静老师你好，就这道题目，我特地查了字典，with可以表示一件事情的factor和这件事情的关系的，换句话说，C选项我读到with，我第一反应就是自动就理解为后面的两个条件（factor）是导致output tripled的原因，所以认为这句话即处理了因果关系也表达了两个factor之前的并列关系。麻烦老师指出我的语法理解问题
