The statement that is NOT a limitation of science is 2. science is always changing.
While it's true that scientific understanding evolves over time as new evidence is gathered and new theories are developed, this is not considered a limitation of science. Instead, it reflects the dynamic and self-correcting nature of the scientific process.
The other options represent actual limitations or challenges associated with scientific inquiry:
- Science requires a lot of money for scientific investigation - This can be a limitation as funding constraints can impact the scope and breadth of research.
- Science cannot make value judgements - Science focuses on empirical evidence and observations, and does not address moral or ethical questions.
- Science can almost replicate natural events, but is not exact - This acknowledges that while science can model and approximate natural phenomena, it may not capture every aspect perfectly.
Therefore, option 2 is the only one that does not represent a limitation.
