Well, I guess we do not consider a hurricane or the Gulf Stream everyday objects. However those of us who spend most of our lives at sea have a different perspective from your science text writer.
If you normally weigh 100 pounds and you stand on a sale while accelerating upward at 9.81 m/s^2 the scale will read 200 pounds. F = m a so
F up from scale - weight down = + m a
and therefore
F up from scale = weight down + 9.81 m = 2 m g
The effect of the Coriolis force is not very noticeable on everyday objects moving along the Earth's surface.
T or F
For the apparent weight of a passenger in an elevator to be equal to zero,the elevator must accelerate upward at 9.80 m/s2.

Just to make sure I understand, both are false right?
The first one would be considered true by a landlubber.
The second one is false. You have to cut the cable and accelerate down at 1 g to show not weight on the scale.
The second one is false. You have to cut the cable and accelerate down at 1 g to show not weight on the scale.
( Assuming the landlubber is not a meteorologist into tracking high and low pressures and resulting winds )
In other words. I think the question is questionable.
