$1.$Demonstrate that the following sentential operator is NOT truth$-$

functional:

Hitler was probably pretty pissed off when he found out that $\_\_\_\_\_\_\_\_\_\_.$

$2.$Unit $3$: $1$bdjlr$,2$bdf$,3$dj $($show your work$*)$

$3.$Unit $4$: $1$bfh $($provide a dictionary and symbolization$)$

$4.$Consider the following simple sentences:

K: Knachel is handsome.

D: Donald Trump is handsome.

Assume the following is true:

Not both Knachel and Donald Trump are handsome.

For each formula below, indicate whether it$$s true $($T$),$ false $($F$),$ or of

unknown truth $-$ value $($U$)$ in light of this assumption.

$($i$)$ K

$($ii$)$ D

$($iii$)$ ~K

$($iv$)$ ~D

$($v$)$ K $$ D

$($vi$)$ K $$ D

$($vii$)$ ~K $$ ~D

$($viii$)$ ~K $$ ~D

Now assume that this is true:

Neither Knachel nor Donald Trump is handsome.

For each of the formulas $($i$)($viii$)$ above, indicate whether they$$re true,

false, or unknown in light of this alternative assumption.
