Question

Please someone help me and yes it can be more then one answer but give me your best answer

Answer 1

????

Step-by-step explanation:

None of those seem to be correct to me.

1. Observations are made using the five senses- sight, sound, touch, taste, and smell. So this is invalid.

2. Observations and experiments can both be done anywhere

3. See answer to 2

4. It's cut off? But observations can literally be as simple as looking at a stick and noting that it's brown, so from what I can read, it's invalid.
