Your first option, "I have taken all the stress I can stand.", is a line of dialogue.
Dialogue is speaking/talking. The second and last options cannot be examples of dialogue because they are not being spoken (you can tell by the lack of quotation marks).The third option is also incorrect because it is what is written, as it says "the study reported" (the study does not speak). Therefore, the first option is correct.
B. Plotted is the correct answer. The other words shouldn't have double consonants.
Burn it burn it with because it is not working correctly
“Tricking” and “misleading” are both synonyms and they both have different connotations... “tricking” has more of a negative tone while “misleading” has more of a neutral tone.
(Hope this helps)
