What evidence supports the cartoonist’s perspective about testing? The students have no expressions on their faces, showing that they are not happy about the tests. The exams are huge and are labeled "more tests" and "still more tests," showing that testing is overdone. The student's response to testing is that he is prepared for it, showing that testing works well. The children are paying attention to the test schedule, showing that students are diligent.

cockroaches and rats most likely symbolize in the play is :

to eliminate ambiguous remote or broad reference it is necessary to focus on anaphoric reference. by definition "anaphoric reference means that a word in a text refers back to other ideas in the text for its meaning." the references should be clear and leave no room for ambiguity.

in the first case the pronoun it probably refers to the car but it has not been mentioned before so we should replace it for the car. in doing so the statement becomes clear.

in sentence number   two   the pronoun he refers to charles dickens the author. yet, the first half of the sentence is about the book a tale of two cities. to repair this it would be better to rephrase the first half : after i read   a tale of two cities by dickens, he so as to remove the remote reference.
