I would advise her not to lose any weight at all as according to the skin fold test which measures her body mass index she has 22 percent body fat which is in the normal/healthy weight range. Any BMI between 18.5 to 24.9 is considered healthy. If she really wanted to she could lose the 7 pounds as long as she stays within the healthy BMI levels and doesn't drop any lower than 18.5 but she really doesn't need to.
Should call 911 then give them an aspirin
Not exactly sure but your teeth and saliva break down food before it becomes further broken down in the stomach(churning action and the stomach acid) it then passes to the small intestines as chyme. So with process of elimination it is definitely not C or D. So it is up to you to decide what counts as digesting. It is either A or B even though in real life both make sense
