(IELTS Academic, 28/11/2020)
The given diagram compares stone age cutting tools at 1.4 million and 0.8 million years ago. Overall, the later one appears to be bigger in size and its shape was also better refined with sharper, more uniform edges and a pointed end.
To begin with, tool A, dated 1.4 million years ago, has a height and width of about 7.5 and 3 centimeters respectively, and is around 1-2cm thick. From the front view, there were large random cuts which created rough edges and a tapered end. From the other sides, similar cuts can be seen, and a sharp end was formed at the top of the tool.
Turning to Tool B, we can see that after 0.6 million years, the cutting tool had doubled in size, with a height of about 10 centimeters and a width of slightly over 6 centimeters, whereas it retained a similar thickness. A look from the front and the back of tool B reveals that its outer shape became significantly finer with a sharp pointy top and a smooth curved bottom. Its side view also witnessed a remarkable transformation which made the tool take the shape of a leaf with a sharp edge running across the tool.
