I am looking for some to explain what does this question want from me to do? Determine all true value assignments, if any, for primitive statements $p, q, r, s, t$ that make each of the following compound statements false. Note: Do not answer this question by drawing truth tables. Study the compound statements and THINK about the truth values of the primitive statements. Your answers should be in English sentences. a. $(p \land q) \land r \implies s \lor t$ b. $p \land (q \land r) \implies s \oplus t$ (where $\oplus$ means exclusive or) Please note that I do not want the answer I want some one explains for me what does this question mean and what does it want from me? This is my first math course. So consider that in mind!

$\begingroup$ We could cheat and compute the truth table, but that would be lengthy. Part of the point is that for some sentences, you can, by thinking, determine quickly the limited set of circumstances under which the sentence is false. $\endgroup$
