A, b, and c! i’m sorry if you get this incorrect but i’m sure that it’s right
Answer:
A
Explanation:
(March 16, 1774[1] – 1834) was the inventor of a cast-iron moldboard plow with replaceable parts, the first commercially successful iron moldboard plow
I’m pretty sure the answer is A but if you already ruled that out try B
The answer is D
Consulting their chemistry teacher and other students in class would not be in depth enough, so A and B are not the answers.
While consulting a chemistry textbook will be useful, the scientific journal is not the best choice.
However, the chemistry textbook would be great, and the periodic table of elements os necessary if they are doing a study about it so the best answer would be D.
Hope this helps!
