1) False. Scientists may predict something but realize a difference soon after before the test, so they could definitely change the hypothesis if they want. It’s only AFTER the experiment they cannot. Because a hypothesis is like a “guess” as to what’s going to happen, right?
2) False. A hypothesis can’t be “valid” because it’s literally a prediction.
3) True. Especially if you’re doing a chemistry lab, it’s really important things are done in order or else the product might result as something else you were expecting, or can be very dANGEROUS
4) True. The conclusion must be based on data because it’s the observation that was seen.
Hope this helps!! I could have answered in short form but I just wanted to make them understandable:)

Answer:
Telencephalon
Explanation:
The cerebrum is also known as telencephalon. It is a major part of the brain that houses the cerebral cortex (of both cerebral hemispheres), varying subcortical structures, plus the hippocampus, basal ganglia, and olfactory bulb. In the human brain, it is the uppermost zone of the central nervous system.
The inferior boundaries of the telencephalon are basically located at the diencephalon (e.g. thalamus and hypothalamus) and the brainstem.
The telencephalon houses the BIGGEST part of the brain, the CEREBRUM.
