Ape language must be taught laboriously, word order does not seem to matter to apes, and describing word use like "waterbird" as creative could be the product of trainer assumptions. This may support an argument that trainers of the apes might be a. underestimating the language use of apes. b. misinformed about the process of teaching language use to animals. c. using biased approaches to teaching apes language. d. making biased observations.

Option-(B): Misinformed about the process of teaching language use to animals.

Explanation:

As compared to other living beings apes are more advanced in terms of learning behavior which is more of an instinct due to being the primates. But, humans being are always involved in the different scientific activities or we can say the experimentation on other beings in order to connect to them and have a proper line of communication. But, in this case the trainers are assumed to be misinformed about the process of teaching language use to animals. As, there are missing some crucial data or set of procedures to know more about the set of procedures in order to connect with the Apes.

"girls"

explanation:

a subject of a sentence is a noun or pronoun that shows who/what is performing the action (or verb) of the sentence.

in this case, the sentence states that the girls see. the girls are the ones who are performing the action, so they are the subject.
