How would quartz be useful to someone who is lost in the woods? (site 1)

Quartz is useful if you are lost in the woods because it can help you start a fire. Most people who die in the woods do so because of hypothermia, and the best way to prevent this from happening is by having a fire. Not only would the fire keep you warm, but it would ensure that your clothes stay dry. Fire also lets you keep animals away, and if necessary, cook meat before you eat it.

what are the choices? the multiple choices?

i will answer in the comments after the choices have been said.

uses : -

1.aneroid barometers primarily measure whether pressure is rising or falling.

2.aneroid barometers are often used for reading pressure in homes and recreational boats.  

3.other uses may include barographs in meteorology and altimeters in modern aircraft.  

4.this type of barometer can announce whether a high or low pressure system is coming or whether it is becoming more intense.  

5.there are different types of aneroid barometers, such as the altimeter, which measures altitude, or distance above sea level.  

6.another example is a barograph, which is a modified aneroid barometer that provides constant readings of atmospheric pressure on graph paper.  

7.when used in this capacity, the aneroid barometer can store a week's worth of data.

android diameter a device for measuring atmospheric pressure , often specially calibrated for use as an altimeter ,consisting of a box or chamber partially exhaused of air, having an elastic top and a pointer to indicate the degree of compression of the top caused by the external air
