With reference to one question on composite material and perspective of Form 5 syllabus, is an alloy technically considered as a composite material?

My personal opinion : Alloy is composite material but not compound material.

My answer for 47 is A. What do u think Mr.Jong? Sodium carbonate is the component for soda lime glass. And this glass is not resistant to heat at all. Boron oxide is the component for borosilicate glass and this glass is resistant to heat. This question is quite tricky..  |

Yes, boron oxide should be added to make it to withstand heat. In my opinion, the question is a bit confusing, it be re-phrased : What is the substance that should be added to glass to make it more heat-resistant?
