Zelda: Dr. Ladlow, a research psychologist, has convincingly demonstrated that his theory about the determinants of rat behavior generates consistently accurate predictions about how rats will perform in a maze. On the basis of this evidence, Dr. Ladlow has claimed that his theory is irrefutably correct.
Anson: Then Dr. Ladlow is not a responsible psychologist. Dr. Ladlow’s evidence does not conclusively prove that his theory is correct. Responsible psychologists always accept the possibility that new evidence will show that their theories are incorrect.
Which one of the following can be properly inferred from Anson’s argument

A．Dr. Ladlow’s evidence that his theory generates consistently accurate predictions about how rats will perform in a maze is inaccurate.

B．Psychologists who can derive consistently accurate predictions about how rats will perform in a maze from their theories cannot responsibly conclude that those theories cannot be disproved.

C．No matter how responsible psychologists are, they can never develop correct theoretical explanations.

D．Responsible psychologists do not make predictions about how rats will perform in a maze.

E．(E) Psychologists who accept the possibility that new evidence will show that their theories are incorrect are responsible psychologists.

材料一：我国农村有7亿多人口、2.1亿多个家庭，占我国家庭总量的67.6％。农村消费市场潜力巨大。金融危机日趋严峻，在外需疲软不断加剧、内需潜力亟待挖掘的现状下，国家提出“扩内需应首先扩大农村消费市场”，把扩大农村消费需求摆在“保增长”更加突出的位置。

材料二：进一步拉动农村消费，应注意“好”字当头。如政府“家电下乡”与鼓励家电“以旧换新”的循环经济政策密切配合，优先保障对中低收入家庭的购买补贴。同时，列入“下乡榜”的家电、汽车生产厂家在销售乃至售后服务环节应更多吸收当地劳动力，以增加农民工资性收入，回馈农民消费热情，让农村消费能够更好更快地促进经济发展。

结合上述材料，运用《经济生活》1—2单元的相关知识回答。

（1）谈谈我国把农村消费市场放在更加突出位置的原因。
