Explanation:

To determine the two things needed for a scientific investigation (even if not following the strict scientific method steps), we analyze each option:

• Evidence (B): Scientific investigations require evidence to support or refute hypotheses, as evidence is fundamental to drawing conclusions.
• Observations (D): Observations are the starting point of scientific inquiry, helping to identify phenomena or questions to explore.
• Drawings (A), microscopes (C), and scales (E) are tools or methods, not essential requirements like evidence and observations.

Answer:

B. evidence, D. observations
