| Assignment IV:
| Fig.1.6. The temperature increased / went up slowly / gradually.
Fig.1.7. There was a sharp / steep increase / growth in solar energy production.
Fig.1.8. Rice production dropped / decreased moderately / considerably.

| Assignment V:
| Possible answers:
2) 1. A high carbon steel is a steel containing from 0.55 to 1.20 per cent carbon.
2. Tool steels contain from 1.05 to 1.20 per cent carbon.
3. Mild steel:
A steady increase of carbon percent gives mild steel a greater tensile strength. A gradual rise of carbon percent gives mild steel more hardness.
There is a steady dip in carbon when taking ductility.
Hard steel:
0.83% carbon gives the hard steel the greatest tensile strength. Gradual increase of carbon per cent improves hardness. Ductility decreases considerably.
4. Tin plate is made from low carbon steel.
5. Car springs are made from spring grades.
