The conception of God and nature and of the relation of man to both provided the 18th- century philosophers with their faith in the worth and dignity of the individual man and the efficacy of human reason. The 18th century was the moment in history when men experienced the first flush and freshness of the idea that man is master of his own fate; the moment in history, also, when this emancipating idea, not yet brought to the harsh test of experience, could be accepted with unclouded optimism.
Never had the nature seemed less mysterious, more simply constructed, more open and visible and eager to yield its secrets to common-sense questions. Never had the nature of man seemed less perverse, or the intelligence and will of men more pliable (yielding) to rational persuasion. Never had social and political evils seemed so wholly the result of ignorance and superstition, or so easily corrected by the spread of knowledge and the construction of social institutions on a rational plan.
The first task of political science was to discover the natural rights of man, the second to devise the form of government best suited to secure them. And for accomplishing this high task, for creating and maintaining a society founded on justice and equality, the essential freedom was freedom of the mind.

The tone of this passage is ______ .

A.neutral and scholarly

B.eloquent and articulate

C.upbeat and enthusiastic

D.balanced and optimistic

某公司的资本结构由债券和普通股组成,债券数量为25万张(面值100元/张,票面利率为8%,每年付息一次),普通股500万股。债券目前的市价为120元/张,筹资费率为4%。目前普通股每股市价为12元,预期第一年的股利为1.5元,以后每年以固定的增长率3%增长,不考虑普通股筹资费率,企业适用的所得税税率为25%。企业拟增资2000万元(不考虑筹资赞用),有以下两个方案可供选择:
方案一:全部按面值发行债券筹集,债券年利率为10%;同时由于企业风险的增加,普通股的市价降为11元/股;
方案二:按面值发行债券筹集1340万元,债券年利率为9%;同时按照11元/股的价格发行普通股股票筹集660万元资金。
[要求] (计算加权平均资本成本时,按照市场价值权数计算):

假设筹资后打算投资于某项目,在对该项目投资进行测算时,得出如下结果:当折现率分别为11%、12%和13%时,其净现值分别为217.3128万元、39.3177万元、-30.1907万元。根据该项目的内部收益率判断该项目是否具有可行性。
