I think i got the problem with question (2).

I also chose E but i see my mistake now - this answer states that the demonstrator(!) hens altered their behavior... Do remember that with social learning, the wanted affect is for the "observers" to change their behavior, not the "demonstrators". Moreover, in the experiment, Sherwin's team wanted to see a change in the observing hens' behavior, and doesn't say anything about changes in the behavior of hens who ate noxious/tasty food.

Where as with answer choice D, we cannot argue about the fact that the demonstrator hens (the ones who actually did the eating) reacted in a bad way to some of the new food (novel food). From the text: " Even when demonstrator hens reacted with obvious disgust to a specific food".

therefor answer choice D is correct, and not E.

P.S if in answer choice E it would have said "The observer hens altered..." that would probably be the correct answer

Hey..

Let us take both the options to understand better.

(D) Demonstrator hens reacted adversely to ingesting certain novel foods.
(E) Demonstrator hens altered their behavior less obviously in response to noxious foods than in response to highly palatable foods.

Since the question is an inference question, the right answer choice needs to be 100% true based on the information given in the passage.

Option E talks about "noxious foods" - The concept of harmful food is not discussed in the passage. Also the option says that the hens altered their behavior LESS obviously - This is a complete contradiction to what is given in the passage.

Hope that helps.

Thanks,

Dear All

Q2, almost every expert below confirms answer is E but the OA indexed confirms as option D being answer. I myself have clicked E for very similar reasons which have been mentioned by 2 experts in the trail but the answer choice indexed seemed different and hence am confused, please can you confirm ?

Also, please can you confirm rationale for answer of Q3 please. I had chosen C as per my understanding the experiment does showcase that social behaviour exists for both aversion and like-ability( observers enjoyed and hogged more food which demonstrators seemed to enjoy). Am happy if someone advises me where and how I could have interpreted this incorrectly.

Thanks as always.

Which of the following best describes the main purpose of the first paragraph of the passage?

• It explains why a particular behavior discussed in the remainder of the passage is beneficial to the animals that engage in it.
• It introduces a concept that has been widely misunderstood among nonscientists.
• It outlines the types of studies that have been conducted to investigate a certain animal behavior.
• It provides information necessary to understand the nature of the phenomenon discussed in the remainder of the passage.
• It describes a viewpoint that is called into question later in the passage.

According to the passage, Sherwin’s research team speculated that the social learning of unpalatability within a particular species might be discouraged if the animals

• did not suffer serious effects from any noxious or toxic foods they ingested
• consumed food in small quantities throughout the day rather than in a few large feedings
• had an unusually large variety of foods available to them
• interacted after feeding as well as during feeding
• did not show signs of illness until considerable time had passed following the ingestion of noxious or toxic food

The passage indicates that which of the following is true about studies of social learning in mammals?

• Such studies have only rarely demonstrated a capacity among mammals to learn to prefer certain foods via observation of other animals.
• Such studies have suggested that in mammals one function of social learning is to establish preferences for novel foods.
• Such studies have demonstrated some capacity among mammals to learn via observation of other animals to avoid ingestion of toxic substances.
• Such studies have been conducted primarily in the mammals’ natural habitats rather than in laboratory settings.
• Such studies have focused primarily on forms of social learning other than the acquisition of preferences for novel foods.
