问题 不定项选择

某甲为耕田,到某乙的养牛场去购买一头牛。据此,请回答下列问题。

双方的约定同上,只是,当晚,某乙不舍得该牛被买走,遂另外换了一头牛放在牛棚里,结果被倒塌的牛棚压死,造成1400元的损失。则下列说法中,错误的有:

A.甲、乙之间的合同之债已经履行完毕,因为,他们已经把履行的标的选定

B.甲、乙之间的合同之债没有履行完毕,因为,某乙变更了给付物

C.在某乙换牛之前,合同之债已经履行完毕,但换牛之后,构成债的不履行,所以,损失应由某乙承担

D.损失应由某乙承担,但由于某甲已经确定丁履行的标的物,若不是某乙换牛,受到损失的足某甲,故某甲也应分担部分损失周某因个人购买房屋向王某借款20万元。双方约定由李某作为保证人,周某并提供了刘某的一辆价值10万元的夏利小轿车作为抵押,双方办理了抵押登记。据此,回答下列问题。

答案

参考答案:A,B,C,D

解析:正如以上分析,甲、乙之间的合同之债没有履行完毕,故A选项错误,B选项虽然结论正确,但理由错误.C选项错误,D选项错误,因为风险损失与该买卖合同无关,某乙承担该风险损失的理由是所有权人承担风险。

People have good reason to care about the welfare of animals. Ever since the Enlightenment, their treatment has been seen as a measure of mankind’s humanity. It is no coincidence that William Wilberforce and Sir Thomas Foxwell Buxton, two leaders of the movement to abolish the slave trade, helped found the Royal Society for the Prevention of Cruelty to Animals in the 1820s. An increasing number of people go further: mankind has a duty not to cause pain to animals that have the capacity to suffer. Both views have led people gradually to extend treatment once reserved for mankind to other species.

But when everyday lives are measured against such principles, they are fraught with contradictions. Those who would never dream of caging their cats and dogs guzzle bacon and eggs from ghastly factory farms. The abattoir and the cattle truck are secret places safely hidden from the meat-eater’s gaze and the child’s story book. Plenty of people who denounce the fur-trade (much of which is from farmed animals) quite happily wear leather (also from farmed animals).

Perhaps the inconsistency is understandable. After hundreds of years of thinking about it, people cannot agree on a system of rights for each other, so the ground is bound to get shakier still when animals are included. The trouble is that confusion and contradiction open the way to the extremist. And because scientific research is remote from most people’s lives, it is particularly vulnerable to their campaigns.

In fact, science should be the last target, wherever you draw the boundaries of animal welfare. For one thing, there is rarely an alternative to using animals in research. If there were, scientists would grasp it, because animal research is expensive and encircled by regulations. Animal research is also for a higher purpose than a full belly or an elegant outfit. The world needs new medicines and surgical procedures just as it needs the unknowable fruits of pure research.

And science is, by and large, kind to its animals. The couple of million (mainly rats and mice) that die in Britain’s laboratories are far better looked- after and far more humanely killed than the billion or so (mainly chickens ) on Britain’s farms. Indeed, if Darley Oaks makes up its loss of guinea pigs with turkeys or dairy cows, you can be fairly sure animal welfare in Britain has just taken a step backwards.

It can be inferred from the third paragraph that()

A. the public’s ignorance of scientific research results in attacks on science

B. a measure of mankind’s humanity is taken into account

C. confusion and contradiction result from vulnerable campaigns

D. the debate is bound to aggravate in the next decade
