Test: Crop production / Agriculture

20 questions

Question 1: The study materials indicate that polytunnels are primarily used for salad crop production exclusively in hot and dry climates.

A. Yes

B. No

Explanation: The study materials describe polytunnels being used for salads in hot, dry Almeria, Spain, but also mention 'winter salad crops are growing inside' polytunnels on a snowy day in Eastern England, indicating their use in varied extreme conditions, not exclusively hot and dry ones.

Question 2: Successful growth for crop plants requires both sufficient light for photosynthesis and a temperature adequate for enzyme activity.

A. Yes

B. No

Explanation: Plants require light for photosynthesis and a temperature warm enough for enzyme activity to grow successfully, as stated in the study materials.

Question 3: Crops are grown for purposes beyond just food, such as providing materials like cotton or hemp.

A. Yes

B. No

Explanation: The study materials state that 'Other kinds of crops are also grown – some to provide... materials (such as cotton or hemp).'

Question 4: Growers manipulate factors such as soil pH and air humidity to increase crop yield.

A. Yes

B. No

Explanation: The study materials state that growers manipulate water, mineral ions from the soil, carbon dioxide, light, and temperature to increase crop yield. Soil pH and air humidity are not mentioned as factors growers manipulate for this purpose.

Question 5: Increasing the overall amount of soil used for planting is a primary method growers manipulate to significantly increase crop yield, according to the study materials.

A. Yes

B. No

Explanation: The study materials list manipulating water, mineral ions from the soil, carbon dioxide, light, and temperature as ways growers increase crop yield. Additionally, reducing losses from pests, weeds, and disease is mentioned. Increasing the overall amount of soil is not cited as a method for growers to manipulate to increase yield.
