Answer

Answer:

  • He should test the acidity of different parts of the lemon, including the juice, pulp, and skin.
  • He should make identical stains on T - shirts and see whether different parts of the lemon will remove the stain.

Brief Explanations:

To test his hypothesis that only lemon juice (due to its acidity) removes stains, he needs to test acidity of different lemon parts and compare stain - removing ability of different lemon parts. Opinion polls and literature from housekeeping sites are not scientific tests. Comparing with other acidic juices doesn't test if only lemon juice in lemon is effective.
