A deposit of sediment that marks the farthest forward advance of a glacier is called a

medial moraine.

terminal moraine.

lateral moraine.

glacial till.

B.

Explanation:

Supraglacial (on top of the ice)

englacial (within the ice)

sediments that slide off the melting front of a stationary glacier can form a ridge of unsorted sediments called an end moraine.

The end moraine that represents the farthest advance of the glacier is a terminal moraine.

Sediments transported and deposited by glacial ice are known as till.

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
