Hi everybody. I'm having trouble with these sentences: 19. The modern racing bicycle is carefully engineered for safely, lightness, and reliable. I know that ‘’reliable’’ is the problem here. But why? Is it parallel structure topic? What are ‘’safely, lightness and reliable’’? Nouns, adjectives or adverbs? 24. Human skin is a complex, sensitive organ that serves many functions necessary for the maintain of life. I think it’s ‘’maintain’’. But why? 25. Space photography and advanced measurement technology, including a laser reflector placed on the Moon, have possible made extremely precise measurements of the surfaces of the Earth. Again, I know that ‘’have possible made’’ is wrong. But why? 26. The scale of the demographic change that are now occurring and that are projected for the near future is unprecedented in human history. The problem is ‘’change’’. Any explanation? Thanks for the help. Ilan
