Answer:
a. People made tools by chipping flint pebbles into blades and scrapers that had sharp edges.
Explanation:
The Upper Paleolithic Period roughly coincides with the last glaciation. The Cro-Magnon man, who emerged around 40,000 BC, is the characteristic representative of the period. This subspecies of Homo sapiens has been divided into several local cultures, distributed throughout Spain, southern France and central-eastern Europe.
The Cro-Magnon were still collectors, hunters and fishermen. Their instruments, however, underwent transformations. As ice made it difficult to obtain stones, various utensils began to be made with bones and ivory; the bow and arrow arose during this period, as did harpoons and needles.
Partly because of the long time spent inside the caves, but thanks mainly to the development of their own intelligence, the Upper Paleolithic men began artistic production by painting animals and hunting scenes on cave walls. This rock art (that is, painted or engraved in the rock), besides its realistic conception, had a magical function because, in executing it, the man believed to be guaranteeing abundant hunting for his group.
Around the same time as the Paleolithic Period, a few inches tall female ivory figurines began to be carved, which experts today call Venus (named after the Greco-Roman goddess of love and feminine beauty). These figures had full breasts and exaggerated hips, which certainly linked them to the idea of fertility.
