Question

read this partial summary of the article \botswanas zebras on the move.\

during the rainy season, zebras travel in large herds across botswana in search of food and water. in the 1960s, to help the cattle industry, the government reshaped the land with the introduction of large-scale fencing that divided up the country. one consequence of the fences was that wild animals could not complete their annual migrations. the researchers astounded to discover that the zebras returned to migration patterns that had been blocked for decades. the spectacle of migration has resumed, to the delight of ordinary and experts alike.

which sentence should be included to create a complete summary of the article?

a the winter season in africa is typically from january to april.
b this fencing is usually known as veterinary fencing.
c after parts of a fence were removed in 2004, researchers tagged zebras to study their movements.
d the makgadikgadi salt pan is a 360-mile round trip from the okavango delta.

Analyze the summary gap

The summary describes a sequence of events:

1. Zebras migrated during the rainy season.
2. In the 1960s, large-scale fencing was introduced to help the cattle industry.
3. A consequence was that wild animals could not complete their migrations.
4. [Missing Information]
5. Researchers were astounded to discover that zebras returned to migration patterns.
6. The spectacle of migration has resumed.

There is a logical gap between the fences blocking migration (Step 3) and the zebras suddenly resuming migration (Step 5). The missing sentence must explain what changed to allow the migration to resume.

Evaluate the options

• (A) "The winter season in Africa is typically from January to April." This is a minor background detail that does not address how the migration barrier was resolved.
• (B) "This fencing is usually known as veterinary fencing." This provides a definition/label but does not bridge the gap between blocked migration and resumed migration.
• (C) "After parts of a fence were removed in 2004, researchers tagged zebras to study their movements." This directly explains the cause of the resumption (removal of the fence) and introduces the researchers mentioned in the next sentence.
• (D) "The Makgadikgadi Salt Pan is a 360-mile round trip..." This is a geographical detail that does not explain the logical transition.

Select the correct option

Option (C) provides the necessary transition to make the summary complete and logically coherent.
