Marcus, Sofia, and Arun are talking about how to separate a mixture of sugar and water.

Do you agree or disagree their ideas?

• I agree with Marcus, because the material that disolve in water cannot separate by filtration

• I agree with Sofia, because the sugar will stay on the filter paper and only water can pass through the filter paper

• I agree with Arun, because some sugar cannot disolve in water, so some of them should be stay in the filter

• I don't agree with three of them, because sugar and water mixture cannot be separated using filter paper, we have to use sieve
