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 pair of scissors always has ______."
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Two blades
The answer must hold for every pair of scissors, without exception. An option that is present in most cases but can be missing in even one case is not always true.
Option (1) Plastic handles — a tailor's scissors are often all metal.
Option (2) Pointed tips — children's safety scissors have rounded tips.
Option (3) Blades 15 cm long — small nail scissors have blades of only a few centimetres.
Option (4) Two blades — scissors cut by two blades joined at a pivot that slide against each other; a single blade is a knife, not scissors, so this is always true.
