Please answer this: I can use this background: Hypertension , which is also called "high blood pressure," occurs when a person’s blood pressure is always high. Hypertension is said to be present when a person's systolic blood pressure is always 140 or higher, and/or if the person's diastolic blood pressure is always 90 or higher. Having hypertension increases a person’s chance for developing heart disease, having a stroke, or suffering from other serious cardiovascular diseases. Hypertension often does not have any symptoms, so a person may not know that he or she has high blood pressure. For this reason, hypertension is often called the "silent killer." Treatments for hypertension include diet changes, exercise, and medication. Foods thought to lower blood pressure include skim milk, spinach, beans, bananas and dark chocolate.  Now, I have a new situation: Dirk went to the doctor because he was feeling dizzy. The doc told him he has Hypertension. His wife,  Mary went to the doctor the following week, and the doc said her blood pressure was normal.  Answer this question please: Which patient had a systolic blood pressure always 140 or higher?

Answer: Dirk


Please answer this: I can use this background: The brains of all mammals have a unique layer of nerve cells covering the cerebrum. This layer is called the neocortex (the pink region of the brains in Figure above ). The neocortex plays an important role in many complex brain functions. In some mammals, such as rats, the neocortex is relatively smooth. In other mammals, especially humans, the neocortex has many folds. The folds increase the surface area of the neocortex. The larger this area is, the greater the mental abilities of an animal.  Now, I have a new situation: Two students read about brains in the animal kingdom. Tom read more about the brains of mammals, while Reed learned more about the brains of amphibians.  Answer this question please: Which student learned more about many complex brain functions?
++++++++
Answer: Tom


Please answer this: I can use this background: Depleted soils can be protected from soil erosion by groundcover plants such as naturally growing grasses in agroforestry systems. These help to stabilise the soil as they increase cover compared to short-cycle cropping systems. Soil cover is a crucial factor in preventing erosion. Cleaner water through reduced nutrient and soil surface runoff can be a further advantage of agroforestry. The runoff can be reduced by decreasing its velocity and increasing infiltration into the soil. Compared to row-cropped fields nutrient uptake can be higher and reduce nutrient loss into streams.Further advantages concerning plant growth:  Now, I have a new situation: Gary and Joe are two farmers. Joe's  farm has a depleted soil, while Gary started agroforestry a few years back, and grows cover crops.  Answer this question please: Which farmer didn't reduce nutrient runoff from his farm?
++++++++
Answer:
Joe
