<\/div>\n\n

Note: If B \u2227 C had been an answer choice, that would have been correct, too. TFL lacks the nuance of natural languages like English, where sometimes a different order can convey different meaning--for example sometimes temporal order is implied in an 'and' claim: 'I turned off the light and went to sleep'. Compare: 'Jenna stomped on my foot and apologized' vs. \"Jenna apologized, and stomped on my foot.' Not so in TFL. Conjunction is true whenever both sides are true. B \u2227 C is logically equivalent to C \u2227 B.<\/div>\n","notChosenFeedback":"
