The 1 strip comic portrays a classroom. Raise hypotheses: What was the subject of the class? Justify your answer
In the Green box it is written, employees are needed, good movies are watched, houses are sold
The subject of the class is ENGLISH. I knew this due to the dialogue between the characters.
The dialogue goes:
quem chegou? - WHO ARRIVE
o sujeito indetermindo - THE INDETERMINATE SUBJECT
On the green box, the terms employees, movies, and houses are the subjects of the sentence. They are also indeterminate because their is no term used to specify which employee, movie, or house.
