If other conditions remain the same, what effect will an increase in surface air temperature have on take-off distance required?

Distance required increases

An aeroplane climbing out of ground effect (with angle of attack and power setting constant) will suffer reduced climb-out performance. This is a result of

An increase in total drag

Reduced wingtip vortices

Decreased lift

Decreased lift and increased induced drag

Ground effect reduces induced drag by restricting the formation of wingtip vortices. The ground plane limits downwash.

What effect will a headwind have on the angle and rate of climb?

The angle and rate will both increase

The angle will decrease and the rate will increase

The angle will increase and the rate will decrease

The angle will increase and the rate will remain unchanged

Rate of climb is determined by excess power (Pa − Pr), which depends on IAS not groundspeed. Wind does not change IAS, so rate of climb is unaffected.
