Task 01: Map
The diagram below shows the development of the cutting tool in the Stone Age.
The diagram illustrates the development of the cutting tool from two different time periods within the Stone Age.
Although the overall size and shape of the two cutting tools are very similar, the cutting tool from the latter time period shows some distinct improvements.
Tool A is a depiction of a Stone Age cutting tool used approximately 1.4 million years ago, while tool B is from a later part of the Stone Age approximately 0.8 million years ago. Both cutting tools are similar in shape and size, being roughly 10cm in length. However, tool A looks to be quite a crude implement, while tool B appears to have been refined into a more effective cutting device.
From the front and rear view, tool B appears to be much wider than tool A and has a rounder body shape. The cutting edges also appear to be more distinct and symmetrical. The side view shows a distinct difference in the thickness of the two tools, with tool B significantly slimmer than tool A.
Sample Answer 2:
The pictures describe the evolution of Stone Age cutting tools between 1.4 million and 0.8 million years ago. It can be seen that the latter design had seen vast improvements in the size, shape and finishing quality.
Tool A, which dated back to 1.4 million years ago, was rather small and rudimentary. At about 7cm in length, the tool was thin and did not display much craftsmanship. The front and back view were plain with only some slight chiselling effort while the side was rough and not very indicative of a cutting utensil.
Tool B showed many updated features compared to the older version. First of all, it was larger and sturdier due to a better water drop design with a broad base and pointy top. Second, both front and back sides were grounded more evenly and smoothly. Finally, although the tool’s thickness stayed relatively the same after 0.6 million years, the side edge was undoubtedly much more finely sharpened.
Sample Answer 3:
The pictures describe the cutting tools created by our ancestors at two different ages.
Tool A was made approximately 1.4 million years ago. It was like an animal tooth about 8 cm long with a rough surface. It may be easy to hold but it was barely sharp enough. As is shown, the front part of the cutting tool was rather broad, and its top area was a little smaller than the bottom. Seen from the side, it was just as narrow as a stick. Moreover, the back part was much flatter than the front part.
Tool B was widely used 0.8 million years ago. Both of the two tools were made of stone. However, Tool B had been better developed than the previous one. It was about 12 cm long. Its front part had been smoother with many little points, which made it similar to the surface of a diamond. Observed from the side, it had got a very acute top, which was very useful for slicing meats. In addition, the back part was even much flatter than that of the older tool.
