Sociallearning in animals is said to occur when direct or indirect social interactionfacilitates the acquisition of a novel behavior. It usually takes theform of an experienced animal (the demonstrator) performing a behavior suchthat the naïve animal (the observer) subsequently expresses the same behaviorsooner, or more completely, than it would have otherwise. One example ofsocial learning is the acquisition of preferences for novel foods.

Some experiments have suggested that among mammals, social learning facilitatesthe identification of beneficial food items, but that among birds, sociallearning helps animals avoid toxic substances. For example, one study showedthat when red-wing blackbirds observed others consuming a colored food or afood in a distinctly marked container and then becoming ill, they subsequentlyavoided food associated with that color or container. Another experimentshowed that house sparrows consumed less red food after they observed otherseating red food that was treated so as to be noxious. Studies on nonavianspecies have not produced similar results, leading researchers to speculatethat avian social learning may be fundamentally different from that of mammals.

But Sherwin’s recent experiments with domestic hens do not support the notionthat avian social learning necessarily facilitates aversion to novel foods thatare noxious or toxic. Even when demonstrator hens reacted with obviousdisgust to a specific food, via vigorous head shaking and bill wiping, therewas no evidence that observers subsequently avoided eating that food. Sherwin’sresearch team speculated that ecological or social constraints during theevolution of this species might have resulted in there being little benefitfrom the social learning of unpalatability, for instance, selective pressuresfor this mode of learning would be reduced if the birds rarely encounterednoxious or toxic food or rarely interacted after eating such food, or if theconsequences of ingestion were minimal. In a related experiment, the sameresearchers showed that if observer hens watched demonstrator hens reactfavorably to food of a particular color, then observer hens ate more food ofthat color than they ate of food of other colors. These results confirmed thatavian species can develop preferences for palatable food through sociallearning.

The primary purpose of the passage is todiscuss the

techniques used incertain experiments on social learning in birds

reasons for thedifferences between social learning in birds and in mammals

question of how sociallearning manifests itself in birds

basis for a widespreadbelief about a difference in behavior between birds and mammals

possible reasons whybirds may or may not learn from each other in a particular way

答案是E 為啥不是 B 拜托分析下其它選項啊！

Many politicians, business leaders, and scholarsdiscount the role of public policy and emphasize the role of the labor marketwhen explaining employers’ maternity-leave policies, arguing that prior to thepassage of the Family and Medical Leave Act (FMLA) of 1993, employerswere already providing maternity leave in response to the increase in thenumber of women workers. Employers did create maternity-leave programs inthe 1970’s and 1980’
s, but not as a purely voluntaryresponse in the absence of any government mandate. In 1972, the EqualEmployment Opportunity Commission (EEOC) ruled that employers who allowedleaves for disabling medical conditions must also allow them for maternity andthat failure to do so would constitute sex discrimination under the CivilRights Act of 1964. As early as 1973, a survey found that 58 percent oflarge employers had responded with new maternity-leave policies. Becausethe 1972 EEOC ruling was contested in court, the ruling won press attentionthat popularized maternity-leave policies. Yet perhaps because theSupreme Court later struck down the ruling, politicians and scholars have failedto recognize its effects, assuming that employers adopted maternity-leavepolicies in response to the growing feminization of the workforce.

It can be inferred that the author of thepassage would be most likely to agree with which of the following statementsabout government policy?

Government policy isgenerally unaffected by pressures in the labor market.

The impact of a givengovernment policy is generally weakened by sustained press attention.

It is possible for aparticular government policy to continue to have an impact after that policyhas been eliminated.

A given governmentpolicy can be counterproductive when that policy has already unofficially beenimplemented.

The impact of a givengovernment policy is generally weakened when the ruling is contested in court.

答案是C 我真的沒有看到原文里有eliminate這個字！A為什么不正確？

拜托拜托！！！磕頭了！！！
