In this question some words are incorrectly written; here is the complete and correct question:

Which question would be the best high-level scientific question?

A. How many giraffes live in Africa?

B. Who made the first microscope?

C. How long ago did dinosaurs live on Earth?

D. Does the amount of salt in water affect the temperature at which it boils?

The answer to this question is D. Does the amount of salt in water affect the temperature at which it boils?

Explanation:

Scientific questions focus on testing a possible explanation (hypothesis) about a phenomenon or helping scientists to better understand a phenomenon. Moreover, because these are part of the scientific method, high-level questions can only be answered through experimentation or observation and they usually contain two or more variables.

These features occur only in option B because this question can only be answered through experiments; for example, by boiling water with different amounts of salt and recording the boiling temperature; this helps scientists to understand how salt affects certain properties and this includes two variables (the amount of salt vs boiling temperature.)

what makes a hero is someone who tries and acres and then to save people and it’s not their jobs to save them just a normal person that has no experts of saving people would jump in to action without it twice about doing it. me that’s the defection of a hero!

different routes can lead to sammy to different places, with different roads.   if you check a map, you can see the routes.   try to make connections of the places and count how many there are.   hope this : )
