Riana notices her two-year old daughter putting sand in her mouth on the beach. though riana tried to stop her, the baby didn’t stop. what do you think riana should do? let the baby continue with her behavior try to explain to the baby how microbes in the sand can spread diseases shout at her baby loudly tell the baby to stop the behavior because she says so

The best thing to do is is shout at the baby loudly

You definitely wouldn't let the baby continue the behavior because you're trying to stop her
You wouldn't explain to the baby about microbes because of course the baby don't understand what a microbe is
You wouldn't tell the baby to stop because she :(Riana) say so because she tried teling the baby to stop and it didn't work

Well if you pick a machine to work on and that's gonna be your exercise if you don't stick to that machine your muscle strength your muscle mass rather will change because you haven't been doing it you change something in your exercise routine which changes your body's form of dealing with things for example you might become weaker or stronger depending on what kind of exercises you do in whether or not the machine you picked actually your muscles grow.
