Use the information given in the chart or graph to determine the truth values of the simple statements. Then determine the truth value of the compound statement given.
-$$\begin{array}{l}
\text { Planet X }\
\begin{array} { c c c c }
\hline \bullet & \text { Moon 1 } & & \
\text { o } & \text { Moon 2 } & \text { Diameter of moons: } & \text { May have: } \
\text { o } & \text { Moon 3 } & \circ 4 - 7 \mathrm {~km} & \text { o water ice } \
\circ & \text { Moon 4 } & \circ 8 - 14 \mathrm {~km} & \bullet \text { atmosphere } \
\circ & \text { Moon 5 } & \bullet 15 - 23 \mathrm {~km} & \circ \text { both }
\end{array}
\end{array}$$
If Moon 4 has a diameter of 8-14 km or Planet X has four moons, then Moon 1 may have water ice.
