This isn't neccessarily true. Your introduction can still make sense without the hook, and the information inside the introduction part should really not directly depend on the hook to explain them, they should either be self explanatory, or you should explain them there.
Hopefully this helps!
There is extraneous information in the diagram. There is duplicate information where you have... There are rivers flowing beneath our feet... a myth? Can stay because it’s simplified. The information ...Have you ever heard that there are rivers of water flowing underground? Do you think it’s true? should be deleted because it’s duplicating the simplified statement prior. Also, Some rivers, such as the Alpaha River in northern Florida, USA,can disappear underground during low flow periods isn’t relevant to the rest of the diagram. Generally water underground is more like water in a sponge is inaccurate and should be deleted. It states in the diagram later on that the water underground is a filler between the rock particles and soil. I hope this helped you. Sorry I didn’t see it sooner.
