Madam Abike turned … 13 bags of maize at the first harvest

Analyze the question This tests phrasal verbs with "turn." We need the particle that fits the meaning: she produced or yielded 13 bags of maize at harvest.

Explain the concept Look at the common meanings of "turn" with each particle:

• turn on: to switch on, or to attack someone
• turn out: to produce, to result, or to prove to be (e.g., "The factory turns out 500 shoes a day")
• turn up: to appear or arrive
• turn in: to hand over, or to go to bed

Step-by-step solution

1. The sentence is about a harvest and a quantity: "13 bags of maize."
2. The verb needs to mean "produce" or "yield."
3. "Turn on" does not fit, because you cannot switch on bags of maize.
4. "Turn up" means to show up, which does not fit a quantity produced.
5. "Turn in" means to submit, which does not fit the harvest context.
6. "Turn out" means to produce, so "Madam Abike turned out 13 bags of maize at the first harvest" is correct.

Answer: B (out)

Exam tip Remember "turn out = produce." Think of a factory that "turns out" goods, or a farm that "turns out" crops. When you see a phrasal verb question, test each option by replacing the phrase with a single-word meaning (produced, appeared, submitted) and see which fits.
