Step 1: Identify the Starting Point
The most general statement is 3: “States in the Middle East and North Africa can do little on their own...” This sets the context of regional limitation in addressing climate change.
Step 2: Add the Next Logical Statement
Following this, 5 fits well: “Politics often gets in the way of problem solving.” This explains why regional action is limited.
Step 3: Broaden to Global Perspective
Now 1 logically follows: “Some countries are, at least, trying to curb emissions.” This balances the earlier pessimism with some optimism.
Step 4: Give Specific Examples
After establishing the general claim, examples come next: - 2: Morocco’s colossal solar plant. - 4: Saudi Arabia’s ambitious solar plan despite oil exports.
Step 5: Final Sequence
Thus, the logical order is: \[ 3 \;\rightarrow\; 5 \;\rightarrow\; 1 \;\rightarrow\; 2 \;\rightarrow\; 4 \]
Step 6: Conclusion
This corresponds to Option (D).
Final Answer:
\[ \boxed{\text{3, 5, 1, 2, 4}} \]
