Verbal - "Same Meaning"

Example
(mail letter)
(pole stake)

On the answer sheet you are given five words to choose from.
A stick B parcel C gamble D post E half
These questions should be answered directly from the answer sheet.
You are looking for a word with a “double meaning” that goes equally well with both pairs of words in the brackets.
Compare the answer options with the words in the first set of brackets and see if they have the same meaning. If they do have the same meaning, then compare the answer option with the words in the second set of brackets.
“stick” does not have the same meaning as “mail”
“parcel” does have the same meaning as “mail”, but does not have the same meaning as “letter”.
“gamble” does not have the same meaning as “mail”.
“post” does have the same meaning as “mail” and “letter” and it also has the same meaning as “pole” and “stake”.
Therefore the correct answer is answer option “D”, post.
You do not have to check answer option “E”, because there will only be one correct answer.
