Q. 41. Basaltic Lava,   Q.43. Basaltic magma  Q.44. False

Explanation:

Basalt is a mafic extrusive igneous rock, formed by the rapid cooling of Mg and Fe rich lava, exposed at or near the surface of the earth. Thus forming about 90% of the surface lava on earth.

Shield Volcanoes emit lava or magma in the form of viscous basaltic lava. Highly explosive.

Greenland and Antarctica together constitute the 99% of the earth ice caps so, Greenland has about 80% cover as compared to antarctic 98% and both are depleting fast.

d. new methods of assembly are introduced.

explanation:

this allows for the goods to be made on a larger scale. not faster because now it is shown to be made better, hence the greater productivity in the question. it is calling for something new to be introduced.
