Here is question in objective form. I have tried answering it but am confused with the answer I got. Instruction: shade A if only IV is correct. Shade B if only I and III are correct. Shade C if only III and IV are correct. Shade D if I, II, III are correct. Shade E if only I, II, III and IV are correct. The question: pitch and asphalt are residual products from the fractional distilation of petroleum. These substances are used as I. protective coatings for road surfaces. II. binding agents for roofing materials. III. organic solvent. IV. catalyst cracking. If this problem is set before you, which of the options lettered A-E will you shade and why. Please explain in detail. Thank you.
