Please help me ASAP: Read and then write a paragraph answering the question.
Tikal lies deep in the jungle in the Peten province of Guatemala, directly between the headwaters of rivers flowing east to the Caribbean coast and west to the Gulf of Mexico. Tikal had access to both coasts, but was protected from powerful non-Maya groups by its remoteness. It is situated on high ground surrounded by large, swampy depressions, which protected Tikal from neighboring cities.

Tikal was a city-state governed by kings. Its huge public buildings included royal residences, offices markets, and giant temple-pyramids. Inside the temple shown here archeologists discovered the tomb of one of the Tikal’s kings, Lord Cacao. His tomb is rich in trade goods from the Atlantic and Pacific coasts.

Although tikal was one of the largest of all Maya cities, it had no local source of water. For water consumption during the dry season, it depended completely on artificial reservoirs dispersed through the city. Building and maintaining these large reservoirs required a great deal of labor and technical administration. There is evidence that a few people continued to live in the main buildings of Tikal for another hundred years or so after its collapse, but hey lived primitively and could not maintain the water system.

Question: Why do you think Tikal collapsed? Please use evidence from the previous passage to support your answer and highlight that evidence.
