1.a
I would presume this to be sufficent due to the fact that Elisa's sleep journal states that she has gotten 9 hours of sleep for the past month thus she is having the same amount of sleep and there is probably another conclusion.
2.b
this information is not sufficient because there is the only information of the amount of time that she slept the night before she went to the office and there could have been a different amount of time that she slept the days before therefore making this information insufficient.
3:a
this information is sufficient because Elisa states the amount of servings that she eats and tells the number of servings that have either protein or starch.
4.b
this is insufficient evidence because there is no information telling what else Elisa ate and what type of food it was which could have been a factor of her being tired.
5.b
I would consider this evidence as insufficient because Elisa only states that she ate well and slept a lot rather than stating the amount of time that she slept and the type of food that she ate because those can be a factor in her feeling tired.
