Question

which source should be avoided when conducting scientific research?
a encyclopedias
b personal blogs
c scientific journals
d governmental websites

Explanation:

When conducting scientific research, sources should be reliable, objective, and based on verified information. Personal blogs often contain personal opinions, unsubstantiated claims, or non - peer - reviewed content, which lack the rigor required for scientific research. Encyclopedias can provide general overviews, scientific journals have peer - reviewed research, and governmental websites can offer official and reliable data. So personal blogs are the source that should be avoided.

B. personal blogs
