Answer 1

.

the pencil as the pencil posed many threats in space i.e. Zero Gravity conditions.
The Graphite present in the pencils was prone to cause a disturbance in the electrical conduction of the intricately designed systems.
The graphite in the pencils had a tendency to cause explosions or a fire due to the graphite particles.
