Four houses have been built along the banks of a small lake. unfortunately for the homeowners, a new dam will slowly raise the level of the lake. in what order will the houses be flooded? a. house d will be flooded first, followed by a, then c, and last b. b. house c will be flooded first, followed by b, then a, and last d. c. house a will be flooded first, followed by c, then d, and last b. d. house a will be flooded first, followed by b, then d, and last c.

Hi,
the order in which the houses will be flooded is A C D B, therefore the answer is letter C. You can see it looking at the lines drawn on the map, that show delimitation of areas with the same altitude from water level. The stripe of land closer to the water will be the first to be flooded.

Hope this helps! If my answer was not clear enough or you’d like further explanation please let me know. Also, English is not my first language, so I’m sorry for any mistake.
