By 2030, 60 per cent of the world population will be living in cities - Fill in the blanks
Answer: Let’s go through each blank and choose the most appropriate option.
16. Authorities (16) more and more global challenges in urban locations.
The blank here should be filled with a phrase that suggests an increasing level of challenges that authorities will face. Option C “will have to face” fits well for the future tense and the context of facing increasing challenges.
17. These challenges (17), among others, pollution, lack of access to clean water, heavy traffic, crowded underground stations, and huge amounts of garbage.
The blank here discusses incorporating different kinds of challenges. Option A “may include” suits the context, providing a sense that these are examples of potential challenges.
18. it is clear that we (18) the growth of cities unplanned.
The blank here should be filled with an action that we are already doing regarding city growth. Option D “can’t have left” fits well, implying it’s clear that the growth has not been left unplanned by mistake.
19. Questions like how, by whom, and to what end this planning (19), however,
This relates to the manner in which planning is done. The best fit is Option B, “was to include.”
20. still (20).
The final sentence needs to end in a way that reflects the enduring or ongoing nature of the question. Option E “must be leaving” somewhat fits but does not provide the ongoing sense of uncertainty.
Therefore the options would be:
- 16 C) will have to face
- 17 A) may include
- 18 D) can’t have left
The questions 19 and 20 are not perfectly clear from the given options. The text could benefit from re-evaluating these if more context is provided.
Depending on the full context, slight variations or re-evaluations may be necessary for steps 19 and 20, and they weren’t entirely clear from the given provided text. If you’re looking for a different perspective or another part of the text to review the options for 19 and 20, I would be happy to assist!
