Answer:
Explanation:
Measuring the amount of deu terium in the universe allows us to set a limit on the density of ordinary matter of universe. Density of the universe is about 9×10-27 kg m-3, because of the way in which deu terium was created in the Big B ang, an exact measurement of the amount of deuterium would allow scientists to set limits on the models of the great explosion.

Explanation:
An astrolabe is an elaborate inclinometer. An inclinometer is an instrument used for angles of slope, elevation, or depression with respect to gravity's direction. It is also used as a tilt sensor, tilt indicator, slope meter, slope gauge.
<em>A. It helped sailors steer around rocky coasts.</em>
Rocky coasts are dangerous. In order to maneuver them, the sailors used an astrolabe. This helped them to understand the angles of slopes, elevation, depression of several rocks on sea.
<em>B. It aided navigators in predicting the weather.</em>
An astrolabe cannot predict the weather.
<em>C. It allowed sailors to know their north-south location.</em>
A compass is used for this purpose.
<em>D. It kept crews from getting sick.</em>
