题目：

阅读下列材料，回答问题。

　　克隆牛“蓓蓓”是我国成功繁殖的首例和第二例胎儿皮肤上皮细胞克隆牛“康康”和“双双”的后代。我国研究人员首先对“康康”和“双双”进行了超数排卵处理，之后，从“双双”体内采集到13枚符合国际胚胎移植标准的可用胚胎(这是国际上首次对体细胞克隆牛进行超数排卵处理实验并获得可用胚胎)。研究人员将这些标准胚胎经过玻璃化超快速冷冻处理后，移植到中国黑白花奶牛“梨花”的子宫内，结果获得妊娠。采用超数排卵技术和玻璃化超快速冷冻技术的“蓓蓓”的降生证明，体细胞克隆牛“康康”和“双双”与正常繁殖的母牛一样，对外来激素具有较好的应答能力；体细胞克隆牛经超数排卵获得的胚胎移植后，具有正常发育成胎儿的能力；“蓓蓓”的降生，证明我国体细胞克隆技术已达到世界前列。

(1)由材料可知，获得“蓓蓓”的生育方式是________________。

(2)根据材料简介，尝试完成产生“蓓蓓”的程序简图：

程序中：①是_____________；②是_____________；③是______________。

(3)根据材料列举你知道的“蓓蓓”出生中用到的生物技术。

(4)本材料中所介绍的生物知识具有哪些积极的社会意义？

I want to divide human understanding into two kinds—classical understanding and romantic understanding. In terms of ultimate truth, a distinction of this sort has little meaning, but it is quite legitimate when one is operating within the classic mode used to discover or create a world of underlying form. The terms classical and romantic, as Phaedrus used them, mean the following:
A classical understanding sees the world primarily as underlying form itself. A romantic understanding sees it primarily in terms of immediate appearance. If you were to show an engine or a mechanical drawing or electronic scheme to a romantic, it is unlikely he would see much of interest in it. It has no appeal because the reality he sees is its surface. Dull, complex lists of names, lines and numbers. Nothing interesting. But if you were to show the same blueprint or give the same description to a classical person, he might look at it and then become fascinated by it because he sees that within the lines and shapes and symbols is a tremendous richness of underlying form.
The romantic mode is primarily inspirational, imaginative, creative, intuitive. Feelings rather than facts predominate. "Art" when it is opposed to "Science" is often romantic. It does not proceed by reason or by laws. It proceeds by feeling, intuition and esthetic conscience. In the northern European cultures the romantic mode is usually associated with femininity, but this is certainly not a necessary association.
The classic mode, by contrast, proceeds by reason and by laws—which are themselves underlying forms of thought and behavior. In the European cultures it is primarily a masculine mode and the fields of science, law and medicine are unattractive to women largely for this reason. Although motorcycle riding is romantic, motorcycle repair and maintenance are purely classic. The dirt gives it such a negative romantic appeal that women never go near it.

From the context of Paragraph 1, we can presume that Phaedrus is most possibly a person _______ .

A．whose mode is classic

B．whose mode is romantic

C．whose mode is unknown here

D．who surely doesn’t have any mode
