IX. Read and translate the short text without any dictionary:

Fact of life:

The continued existence of life depends on reproduction, and this is perhaps the most characteristic feature of living things. Reproduction allows both continuity and change. Over countless generations this has allowed species to become well suited to their environment, and life to evolve gradually to more complex forms.

X. Food for thought:

a) You might be familiar with the mnemonic (memory aid) `Richard Of York Gave Battle In Vain` for remembering the colors of the spectrum – red, orange, yellow, green, blue, indigo, and violet. Suggest a mnemonic for the ten characteristic features of living things described in this unit. You can change the order of the features.

b) Robots can move and respond, and require energy to maintain their organization and a constant internal environment. How would you argue that robots are non-living objects? A robot could be made that has all the characteristic features of living things. Would it still be non-living?
