Final answer:
The title of the book in question is 'Les Halles, Counter-Proposal,' making option 1 the correct answer.
Step-by-step explanation:
The title of the book 'Les Halles, Counter-Proposal' is Les Halles, Counter-Proposal. This means the correct answer to the question is option 1) Les Halles, Counter-Proposal. Without further context, it's difficult to provide additional information about the book, such as its contents or themes. However, the title suggests that it could be related to a proposal or a plan concerning Les Halles, which is a historical market area in Paris, often discussed in urban planning and architecture circles.
If this is an actual book and not a hypothetical example, it would be authored by Greg Walton and might be focused on a counter-proposal to a pre-existing plan or development for the Les Halles market. The option 3) 1970s might provide a hint to the historical period discussed in the book but does not serve as a title. Looking for the book under the name Greg Walton or the year 1970s would not yield the correct work, as those are not titles. Therefore, the information provided indicates that option 1) Les Halles, Counter-Proposal is the title of the book by Greg Walton.
