False. Brittleness refers to a material's tendency to break or shatter under stress rather than deform, indicating that it lacks toughness. While brittle materials can be strong under certain conditions, they are not able to absorb energy or withstand impact without failing. Therefore, being brittle generally implies a lack of overall strength in practical applications.

Assuming that you mean not (p or q) if and only if P ~(PVQ)--> P so now construct a truth table, (just place it vertical since i cannot place it vertical through here.) P True True False False Q True False True False (PVQ) True True True False ~(PVQ) False False False True ~(PVQ)-->P True True True False if it's ~(P^Q) -->P then it's, P True True False False Q True False True False (P^Q) True False False False ~(P^Q) False True True True ~(P^Q)-->P True True False False

The presence of a false conclusion in a strong argument suggests that at least one of its premises must be false, as a strong argument should lead to a true conclusion based on true premises.
True. Metalloids look like metals but are brittle and are not good conductors.
