Question 1
Research suggests that the 150-acre complex of pyramids, plazas and residential buildings was a thriving metropolis when Egypt’s great pyramids were still being built. Though discovered in 1905, for years Caral attracted little attention, largely because archaeologists believed the structures were fairly recent.
Caral was built at the same time as the construction of the Egyptian pyramids.
Question 2
2. Shady and her crew searched for broken remains of the pots and containers that most such sites contain. Not finding any only made her more excited: it meant Caral could be what archaeologists term pre-ceramic, that is, existing before the advent in the area of pot-firing techniques.
The absence of pottery at the archaeological dig gave Shady a significant clue to the age of the site.
Question 3
3. Around the perimeter of Caral are a series of smaller mounds and various buildings. These indicate a hierarchy of living arrangements: large, well-kept rooms atop pyramids for the elite, ground-level quarters for craftsmen, and shabbier outlying dwellings for workers.
The remains of housing areas at Caral suggest that there were no class distinctions in residential areas.
Question 4
4. Biodiversity comprises every form of life, from the smallest microbe to the largest animal or plant, the genes that give them their specific characteristics and the ecosystems of which they are a part.
The term ‘biodiversity’ consists of living creatures and environment that they live in.
Question 5
5. Some 1.2 million species of animal and 270,000 species of plant have been classified, but the well-being of only a fraction has been assessed. The resources are simply not available.
There are species that have not been researched because it’s unnecessary to study all creatures.
