Lake Chad is a freshwater lake in west-central Africa. It is bordered by Chad, Cameroon, Niger, and Nigeria. Lake Chad once covered an area of over 25,000 square kilometres in the 1960s. However, it has shrunk dramatically since then, as most of the water from its feeding rivers has been diverted for irrigation before reaching the lake. The lake also loses significant water through evaporation in the surrounding arid climate. Lake Chad has therefore lost the vast majority of its original surface area, and today it survives mainly as a shallow, fragmented remnant of its former size.

AThe fishing communities around Lake Chad have also been severely affected by the lake's decline.
BResearchers view the shrinking of Lake Chad as a major threat to regional food and water security.
CBecause rainfall in the region has become increasingly unpredictable, this water loss is not being replaced fast enough to maintain lake levels.Doğru cevap
DAlso known by other regional names, Lake Chad sits at the meeting point of the Sahara and Sahel regions.
EThe Chari and Logone rivers, mainly used for irrigation, are the lake's two main sources of inflowing water.

Neden?

Boşluktan sonraki cümle 'therefore' ile sonuca varır: göl, yüzeyinin büyük bölümünü yitirmiştir. Bu yüzden boşluk, su kaybının yerine konamadığını belirterek nedensel zinciri tamamlamalıdır; doğru seçenek yağışların düzensizleşmesini gösterir. Balıkçı toplulukları, gıda güvenliği ve gölün konumu seçenekleri bu zinciri kapatmaz.
