Try a few questions
- Practice question 1
The chemical industry mainly supports the textile sector through the production of
- A.agricultural fertilizers exclusively
- B.construction cement exclusively
- C.pharmaceutical drugs exclusively
- D.synthetic fibres, such as nylon and polyester, and textile dyes
Show the answer
