Quiz #30 was a bit tricky. Stick with me here. We use “than” with comparative adjectives, as in “faster than,” “greater than.” etc. “Different” shows distinction, therefor, it takes the preposition, “from,” e.g., “separate from,” “away from.” That makes Fairbanks different from the sun belt states (though climate change has made them oddly similar lately).
Dr. John’s Grammar Quiz #31 Can you spot the glaring grammatical error in this sentence? “His application was fraught with grammatical errors: misplaced commas, missing periods and improper uses of the semicolon.”
