Question: #1: "days" plural. #5: Answer A is incorrect. Answer B is correct. Every grammar site correctly identifies "AT the stop/station" as the correct article in this context. #6: Several errors: + "weekend" misspelled + Answer A (on) alone is correct. + Punctuate with a question mark. #17: Almost always spoken with the blank left open. #18: Sorry, but I have no idea what the sentence is trying to say. #20: Capitalize "May"
