Answer:
A:both ideas could be scientific
Step-by-step explanation:
Both Linda's and Julia's ideas are same and could be scientific because the result or answer that Linda receives is same and equal to the result of Julia. Now Julia is performing some experiment or running some scientific test on her idea and she is getting her result on the basis of that. SO Julia's result is compatible with scientific method. Since Linda's answer is also matching with Julia and is free from bias, therefore both of their ideas could be scientific and not pseudoscientific.
Thus option A is correct.
