You are welcome to post comments, questions, suggestions, alternatives, etc. about today's paper and memorandum in this space. I will ask the examiners to respond to it.

*** New information ***

Q2.1.1

• Scratch "granite counter top". Granite is a heterogeneous mixture.
• Add "paper clip". If a paper clip is made of an alloy such as steel wire, it is a heterogeneous mixture.

Q2.1.2

• Add "granite counter top" here.

Q2.1.4

• Keep "paper clip" here. If it is made of copper, it is fine here. Hence, two answers must be accepted for paper clip.
