You are standing on take-off and you feel the wind coming a bit from the side. Is that a problem for a safe launch?
B is the only correct answer for an Alpine or forward launch in the mountains. When you choose to execute a reverse launch, C is a possibility as well. For a tow launch, sometimes a 90 degree crosswind can be safe to start for more experienced pilots.

Which lines carry the most weight?
Most of the weight is carried by the lines attached to the front of the canopy.

When is the best time to put your legs down during the landing approach?
D is the safest option. The others are either uncomfortable and unwanted because you can't use weightshift anymore, or unsafe if you are too late and land on your bum risking a back injury.
Standing on launch you see a rain shower approaching. Do you take off?
D is the only safe answer. You can never be sure that you have landed before the rain arrives, so C is risky. B is only partly true for light rains, but again you're taking a risk. A is not true, although flying in cloud is illegal in many countries.

Why are the cell openings slightly pointed down?
The cell openings are positioned where the air flow hits the profile of the airfoil.

What happens when you fly too slowly?
Below the minimum speed or stall speed, the wing stops flying and will descend straight down like a parachute. This is a very unstable situation and often leads to a spin or stall.
See the chapters on Aerodynamics (stalls) and Advanced flying.

We lay out the canopy in a semi-circle before take-off. Why?
When the center cells fill first, the canopy will rise steadily and straight.
It's sunny on launch and you're ready to take off, but the wind has been from the back for quite a while. What do you do?
Gliders suffer the most from direct sunlight. The airtight coating is damaged by the UV-radiation. Don't leave your glider out in the sun unnecessarily.
Additionally, sitting on the reserve parachute may damage it without you noticing, so it might fail if you ever need it. Never sit on your harness.

'Big ears' are a descent technique and serve to increase your descent rate. Additionally, in which situation is pulling 'big ears' a good idea?
Pulling big ears reduces the wing area and therefore increases the wing load. This stabilizes the canopy somewhat. It also increases the flying speed but in most cases this is counteracted by the extra drag the ears create.

What do you do when you can't hear the instructor over the radio during a flight?
B is correct, A and C are nonsense of course.
Answer D is the second best choice in case your mind goes blank, you panic and you don't know what to do. It's better to do nothing in that case.
