a) Material life

h) Financial safety and security.

Explanation:

The quality of life is an index that is calculated by using different estimators that covers diverse aspects of human life such as, among others health, safety, happiness, security, transportation, etc. The INEGI (National Institute of Statistics and Geography, Mexico) calculates the quality of life by using the estimators above described (and others). In my opinion, the most important one of this list is political governance, because it is an underlying characteristic that has a direct effect on the further estimators, thereby affecting their performance in a short/medium-term period.

The correct answer is D)

Cycle energy and matter to support the biosphere as a closed energy system

Explanation:  

The earth as we know it is a closed energy system that is, matter cannot be introduced or removed from it. Sometimes, rare meterites enter into the system with minimal or no disruption.

Also, energy can enter and leave. The energy mostly referenced here is the sun.

Within the earths system, the lithosphere, hydrosphere, and biosphere materials and energy go through a cycle which helps to support life.

For example, water when heated up by the sun rises as vapour from the earth and oceans into the atmosphere where it cools and condenses. When it cools and condenses, it , in the form of rain, comes down on the earth and oceans. As rain falls down to the earth and runs off the rocks, rocks are broken down into smaller fragments and soils.  The hydrosphere comprises of all water bodies on earth. Besides the vapours which are evaporated from the same into the atmosphere, when volcanoes erupt they also send vapourised water into the atmosphere.

So because the earth is a closed system, a change in one sphere effects a change in others. An example is a change in the water cycle.
