There is little incentive to improve the economy in centrally-planned economies.

This statement is true.

Explanation:

A centrally planned economy is a system in which all economic decision making is done by the government. The government controls what is to be produced, in which numbers and how the final products should be distributed. There is little or none private ownership and citizens are not allowed to question the government and its decisions.

Therefore, there is little incentive to improve the economy because:

- it is all in hands of the government and the government adjusts the economy according to its needs and liking,

- private citizens do not have a say in economic matters,

- the economy and the state of it is used as a weapon to induce obedience and control on the country's citizens.

well that depends on how deep the hole is. you'd first go through te crust of the earth, then the upper mantle, then the lower mantle then the outer core, then the inner cor then you'd be stuck in the core to melt.
