Answer:
The practice of female infanticide.
Explanation:
Some countries, especially China, India, have practiced female infanticide due to the fact that they regard males as superior. As for China an addition factor might have been the one child rule applied for a long time although this law has been relaxed in the last few years and you can now have 2 children. Also, India is well know for female infanticide and women are less valued and the fetus is aborted.

India has cause to fret. According to two demographers, John Bongaarts and Christophe Guilmoto, a staggering 45m girls and women are missing from the country. Some were never born, having been detected by ultrasound scans and aborted. Others died young as a result of being neglected more than boys. Some villages in the north have an alarming surplus of boys and young men. Yet attitudes and behaviour are changing. In India, and in the world as a whole, the war on baby girls seems to be winding down.
Answer:
At the boundary with the core.
Explanation:
The mantle is the second layer from the top. It is bordered by the lithosphere above it, or rather by the crust, and by the outer core below it. The mantle is a layer which is in viscous state, being mostly consisted of molten metals and rocks. The temperature of this layer is not the same all throughout it, but it varies a lot. The temperature at its top part is around 200 C degrees, while the temperature at its bottom is around 4,000 C degrees. There's two reasons for this. One is that the core is very hot, so it makes the bottom part of the mantle very hot as well, and the other one is that the lithosphere is much cooler, as well as constantly getting new, cold, crust in it, which makes its top part much cooler. The mantle is the layer responsible for the movement of the tectonic plates on the surface, as it is the layer where the convection currents occur and drive the plates' movement.
