Question

1. Jumping a fence of prickly pears, Gumat Hussain, a local chief in the driest district of North Wollo, Ethiopia's most drought-prone province, walks gloomily through his sorghum.
2. This was because of a particularly strong El Niño effect, which this year made swathes of Africa drier than usual, along with a longer-term drying of Ethiopia's climate, especially in the north and east.
3. In many lowland parts of North Wollo, a day's drive north of Addis Ababa, the capital, the annual midsummer rains lasted for under a week.
4. "The crops have not produced grain. They are useless even for the animals,” he sighs. "My oxen and goats will soon die. Our people will wait only for the government to respond.”
5. Now it is harvest time and the tall, green crops belie their fruitlessness.
___

Answer 1

Sentences 2, 4 and 5 cannot start the paragraph as they require a prior context. We are left with 1 or 3. Sentence 3 cannot begin the paragraph as it already assumes that the reader knows about North Wallo. So sentence 1 is the starting sentence. 1 and 4 form a pair as they share the link of Gumat Hussain. Similarly, 3 and 2 are a pair as 2 explains why the annual mid summer rains mentioned in sentence 3 lasted only for a week. Sentence 5 begins a new topic.
So, the correct sequence is 14325.
