Question

1. in an earthquake, why are people advised to hold on to the table or desk they are sheltering under? the shaking of the ground can shift the object youre under. the table or desk can become a projectile if you let go of it. you are likely to fall down if you let go of the table or desk. you may become disoriented by the shaking of the ground.

Explanation:

During an earthquake, the ground shakes. If people do not hold on to the table or desk they are sheltering under, the shaking can shift the object. This could leave them exposed to potential hazards. The other options are less relevant. A table/desk is not likely to become a projectile just because one lets go (it's more about its position relative to the person due to ground - shake). Falling down is more about balance (not directly related to holding the sheltering object in the context of the object's movement). Disorientation is a general effect of shaking but not the main reason for holding the sheltering object.

Answer:

The shaking of the ground can shift the object you're under.
