Questions refer to the following article.Rase Chemical Corporation is proud to submit its entry to the annual Chemistry Innovation in Motion contest to be held in the Royal Park Hotel, Vancouver, Canada, September 6～10.Our entry introduces what we believe is an extraordinary product.
The product is a new type of insulation material providing benefits that traditional housing insulation products do not offer.Thanks to its unique microstructure, the new material can keep houses up to 50 percent warmer in the cold winter months.This means that using our insulation will result in substantial reductions in consumer heating hills.In addition, our new insulation material is made without the harmful chemicals often found in other insulating products, making it safer to use and easier to dispose of.Moreover, the insulation functions well in all types of climates.Consumers living in humid or dry areas will equally benefit from our new insulation.
We invite all scientists and observers to visit our information booth at the Chemistry Innovation in Motion contest and to meet Bernard Cho, CEO of Rase Chemical Corporation, who will be giving a presentation on the product at 9:00 A.M.on September 9.
What can be inferred about the new insulation? A．It is most useful in a small house
B．It represents an innovation in chemistry
C．It needs to be tested in a dry climate
D．It is currently being used at the Royal Park Hotel
