Can we say that older tools have lesser function and newer tools have more

function? Why​

The older tools have been used more, and they are more worn out. For example, is it easier for a 20 year old to run a marathon or a 80 year old? The 80 year old is older, therefore it is harder to function.

last one is the answer

the correct answer is option d. none of these. it is noted that options a, b, and c share the same content.

despite the valid answer provided at the last sentence of each of the options, a question/answer format shouldn't include humourous themed responses such as "you bet your thermal pj's we do." - unless of course, the answer is carried out in an informal environment. this could be replaced with a simple "yes" or "it is necessary".

the question should be re-phrased to a more appropiate syntaxis. instead of "do we need the greenhouse effect? ", it should be written as "is the greenhouse effect necessary? " in order to give it a general scope, instead of limiting the answer to the needs of "we" the humans.
