Answer:
1. A Struggle for Survival
2. survival will reproduce
3. Superior adaptive variation
Explanation:
1. Observation: overproduction of offspring that can possibly survive.
CONCLUSION: A Struggle for Survival, most of this offspring fight for food and water.
2. Observation: variation in species: member of the same species have different ways of identification, which are color, sex, e.t.c
CONCLUSION: Those individuals that survive and reproduce do so in consequence of "superior adaptive variation" (they are "more fit")
3. Observation: Variation heritable through selection: most survival pass there favourable adaptation to their offspring.
CONCLUSION: Superior adaptive variation will be passed on to offspring generation.
