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 heavier smog and pollution in larger cities. However, during the last five years, there were 25 days when the temperature was the 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.

(B) Experts neglected the smog and pollution in smaller cities.

(C) These 25 days of symmetric temperatures were due to different atmospheric fronts.

(D) These 25 days are not representative of normal temperature measurements.

(E) Higher temperatures in larger cities are caused by factors other than smog and pollution.

+1 for D.

(A) The temperature can change very quickly in the course of one hour. --> Irrelevant

(B) Experts neglected the smog and pollution in smaller cities. --> No information given

(C) These 25 days of symmetric temperatures were due to different atmospheric fronts. --> Out of scope

(D) These 25 days are not representative of normal temperature measurements. --> Correct, 25 days out of 5 years is very less a sample to generalize the conclusion in hand

(E) Higher temperatures in larger cities are caused by factors other than smog and pollution. --> Out of scope

Hence, D.

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.Irrelevant point- as there is no mention of rate of change of temperature.

(B) Experts neglected the smog and pollution in smaller cities.Wrong conclusion- as author clearly mentioned "heavier smog and pollution in larger cities". so he/she must have evaluated/compared level of smog and pollution in smaller cities.

(C) These 25 days of symmetric temperatures were due to different atmospheric fronts.Wrong conclusion- as author has not mentioned other factors apart from smog and pollution in smaller cities.

(D) These 25 days are not representative of normal temperature measurements.-correct

(E) Higher temperatures in larger cities are caused by factors other than smog and pollution.Wrong conclusion- as author has not mentioned other factors apart from smog and pollution in smaller cities.

One more with (D)

Quote:

25 days out of 5 years is \(\frac{25}{365*5}*100\) ~ 1.37 % which is a negligible percentage, hence can be rejected.

Answer must be (D)
