Question

what is a main characteristic of sustainable development?
a. prioritizing economic growth over environmental protection
b. meeting present needs without compromising future generations
c. focusing solely on technological advancements
d. depleting natural resources for immediate benefits
which alternative energy source relies on the energy of moving water?
a. biomass energy
b. geothermal energy
c. wind energy
d. hydroelectric power

Explanation:

First Question (Sustainable Development Characteristic)

Sustainable development emphasizes balancing current needs with future generations' ability to meet their needs. Option a is incorrect as it ignores environmental protection. Option c is wrong as it's not solely about technology. Option d is unsustainable. Option b matches the definition of sustainable development.

Hydroelectric power uses the kinetic energy of moving water (like in rivers, dams) to generate electricity. Biomass uses organic matter, geothermal uses Earth's heat, wind uses wind energy. So only hydroelectric relies on moving water energy.

Answer:

b. Meeting present needs without compromising future generations
