Read the following paragraph about renewable energy and complete the sentences using the correct relative pronouns (who, which, whose, where) or linking words.

'Solar energy, $1$. is considered a breakthrough in sustainable development, helps reduce the carbon footprint $2$. is a major goal for many countries. Scientists $3$. work in this field suggest that efficiency will increase by $15\%$ in the next decade, a change $4$. could revolutionize how we power our homes. This technology is particularly effective in regions $5$. the sun shines for more than $2500$ hours per year.'

Analyze the rapid evolution of genetic engineering. Write an argumentative text (150-200 words) discussing how the progress of CRISPR-Cas9, characterized by an exponential growth function $P(t) = P_0 \cdot r^t$ (where $r > 1$ is the innovation rate and $t$ is time in years), challenges international bioethics. You must compare the medical benefits, such as treating $Cystic \ Fibrosis$, with the risks of germline editing. Address how the inequality factor $I = \frac{Wealth_{high}}{Wealth_{low}}$ might lead to a biological class divide.
