Weather records indicate that the temperature in linden , a major metropolis , is always 2 to 3 degrees higher than the temperature in Ipswich , a smaller city close by linden. Experts say that this situation is caused by heaver smog and pollution in larger cities. However, during the last five years , there were 25 days when the temperature was same in both cities.
Which of the following conclusions can be properly drawn from the statement above ?
A The temperature can change very quickly in the course of one hour.
Not sure. Temp. can or cannot change in course of one, two, three, or any number of hours.B Experts neglected the smog and pollution in smaller cities.
Not sure. May be experts neglected or may be experts indeed considered this factor but the actual reason is something else.C These 25 days of symmetric temperatures were due to different atmospheric fronts.
Not Sure. No were in argument this reasoning is mentioned so there could be many reasoning for symmetric temp.D These 25 days are not representative of normal temperature measurements.
Sure. Consider this line in argument - "..is always 2 to 3 degrees higher .. ". This confirms that higher temp in big cities is actually the NORMAL representations. So the non-symmetric temp. of 25 days are NOT normal. E Higher Temperatures in larger cities are caused by factors other than smog and pollution.
Not sure. This may be the factor, or may be the actual cause is something else.
