Directions: Choose the most appropriate word from the options given below to complete the following sentence.

If we manage to ____________ our natural resources, we would leave a better planet for our children.

The sentence discusses natural resources and leaving a better planet for children, indicating preservation and protection. Uphold means to support or maintain (doesn't fit resources). Restrain means to hold back or limit (not the right context). Cherish means to love and protect emotionally (too sentimental for conservation). Conserve means to protect from harm or destruction, use carefully - this perfectly matches the environmental context of managing natural resources for future generations.
