Explanation:

Statement 1 is correct: Temperate grasslands of the mid-latitudes produce the greatest quantity of wheat per capita amongst the world's wheat-growing nations.

• The temperate grasslands are ideal for extensive wheat cultivation.
• They are, naturally the greatest wheat exporters.

Statement 2 is correct: Three-quarters of the world's wheat is winter wheat, i.e. wheat sown in winter or late autumn, and is then harvested in the summer. .

• The cool, moist spring stimulates early growth and the light showers in the ripening period help to swell the grains to ensure a good yield. They warm, sunny summer is not only advantageous for harvesting but also enables the straw to be dried for farm use.
• It is a hard wheat with a low moisture content, being ripened in the hot, sunny, continental summer. It is best for bread-making and is extensively traded.
• Spring wheat is grown in the regions where winter temperature is too cold for wheat seedlings to survive. The yield of spring wheat is hard wheat which is suitable for making cakes.
