Question : Comprehension:
Read the following passage and answer the questions given after it.

Amidst a maze of rocks tucked in the Aravalli mountain ranges of Haryana, a team of archaeologists discovered cave paintings they believe belong to the Upper Palaeolithic age. The cave paintings have been discovered just outside the national capital and a stone's throw away from a holy grove called Mangar Bani, the region's only surviving patch of primary forest.
While the residents of the villages have been familiar with the paintings for ages, the Haryana government's museum and archaeology department took note of them just recently. A fact-finding team was sent to the area in the last week of June. The team came across cave paintings comprising images of human figurines, animals, foliage, and geometric drawings. While some have paled over time, others are still very visible. They also discovered rock art and open-air ceremonial sites.
Banani Bhattacharyya, deputy director of the department of archaeology and museums, informed, "So far, cave paintings in Delhi-NCR have only been found here. The paintings are yet to be dated, but at least some of them belong to the Upper Palaeolithic period in all likelihood. We are viewing the paintings in continuation with the Soanian culture which has been found in Shivalik Hills, Narmada, and Aravallis."
Most of the cave paintings found were in ochre colour, but some were in white. As per experts, cave paintings in white are usually from a later stage (early contemporary era), while Stone Age paintings are more often than not in ochre. "Stone age paintings generally use red and ochre colours. Stones of these colours used to be available locally, and inhabitants crushed the stones for preparing the colour for paintings," added Bhattacharyya.
The Upper Palaeolithic Age began around 40,000 years ago and lasted until around 10,000 years ago. While yet to be established through archaeological dating, Bhattacharyya says the Mangar cave art is $20,000–40,000 years old. Bhattacharyya claimed that the discovery is extremely significant. "Starting from the Lower Palaeolithic to the Middle Palaeolithic and then the Upper Palaeolithic, we see the evolution here. We have found significant remains from the Lower Palaeolithic to the Middle and Upper Palaeolithic periods too," she explained. "Though tools from the Palaeolithic Age have been identified earlier in parts of the Aravallis, it is for the first time that cave paintings and rock art of a large magnitude have been found in Haryana," she added.
