The statement below is followed by four options. Each option is related to the item in the statement, but only one is always true. Select the option that always holds and makes the statement true.
"A week always has ______."
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Seven days
The answer must hold for every week, without exception. An option that is present in most cases but can be missing in even one case is not always true.
Option (1) A festival — many weeks of the year pass without any festival.
Option (2) Seven days — a week is a period of seven days (for example, Sunday to Saturday); there is no week of six or eight days, so this is always true.
Option (3) A full moon — a full moon comes only once in about 29.5 days, so most weeks have no full moon.
Option (4) A rainy day — in the dry season whole weeks pass without any rain.
