Question

the writer wants to provide relevant support for the claim made in sentences 12 and 13. which of the following sentences, if added after sentence 13, would most effectively accomplish this goal? a according to the australian bureau of meteorologys national tidal centre, there has been an average sea - level rise of 7.3 millimeters a year around low - lying islands like kiribati in the past few decades. b a professor of biology at old dominion university, kent carpenter, notes that poaching of giant clams does more damage to marine ecosystems than island building does. c marine biologists contend that the urban sprawl spreading into the oceans inevitably causes havoc for marine organisms and their habitats. d the government of south korea expected to have 300,000 residents in the utopian smart city built on the artificial island of songdo.

Explanation:

Without knowing the content of sentences 12 and 13, we assume the claim is related to sea - level rise or coastal issues. Option A provides data from a reliable source (Australian Bureau of Meteorology's National Tidal Centre) about sea - level rise around low - lying islands, which is likely relevant support. Option B is about poaching of giant clams, Option C is about urban sprawl's impact on marine organisms, and Option D is about the population of an artificial island city, all of which seem less related to a sea - level rise or coastal claim compared to Option A.

Answer:

A. According to the Australian Bureau of Meteorology's National Tidal Centre, there has been an average sea level rise of 7.3 millimeters a year around low - lying islands like Kiribati in the past few decades.
