Reversible reactions and equilibrium — practice question

Methanol is formed when carbon monoxide reacts with hydrogen. This reaction is reversible. $\text{CO}(g) + 2\text{H}_2(g) \rightleftharpoons \text{CH}_3\text{OH}(g)$ The forward reaction releases heat. Which combination of temperature and pressure results in the greatest equilibrium yield of methanol?
