Decide which of the following quoted remarks is an argument and which is an explanation:
3.6.1 A councillor speaks at a council meeting and says, ‘Because our street lights are too dim, we have more accidents and more crime than we should. Furthermore they are so lowthat they are easily and often damaged by vandals. That is why we should get new, bright high-level sodium lights.’
3.6.2 The police have found the body of a woman lying near a footpath; after a post-mortem the pathologist reports, ‘She died because she had a heart attack and no one found her soon enough to help.’
3.6.3 A newspaper reports, ‘Thailand and India have had to fi ght costly legal battles to protect Thailand’s jasmine rice and India’s basmati rice because a company in Texas, called Rice Tec, was granted patents in the United States on varieties of rice it claimed to have developed, which closely resembled the Thai and Indian versions.’
3.6.4 A government spokesperson says, ‘Though investigations are continuing, the trawler which sank suddenly in relatively calm seas last week probably went down because a submarine fouled its nets and dragged it down.’
3.6.5 A financial journalist writes, ‘The bank will almost certainly reduce interest rates at the next opportunity because the economy is slowing down fast, many companies are in great difficulties and demand has fallen off dramatically.’
3.6.6 A seismologist says, ‘There are huge “plates” on the surface of the Earth which press and move against one another. Because there is friction between these plates, they fail to move for many years until the pressure becomes huge and then they move suddenly, an event we experience as an earthquake. That is why San Francisco had a huge earthquake in 1906 and also why they expect another one at any time now.’
