The given statement is 鈥淓very square is a rhombus鈥�

The given additional statement is 鈥�ABCD is a rhombus鈥�.

Hence every square is a rhombus doesn鈥檛 imply that every rhombus is a square.

ConsiderABCD is a rhombus then it may or may not a square, since every square is a rhombus doesn鈥檛 imply that every rhombus is a square.

Hence, conclusion is not possible.

The given statement is 鈥淓very square is a rhombus鈥�

The given additional statement is 鈥淚n quadrilateral LAST, $LA鈮�LT$鈥�.

Here $LA鈮�LT$implies that adjacent sides are not equal.

Since adjacent sides are not equal in the quadrilateral LAST, therefore it cannot be square.

Hence, the conclusion is that LAST cannot be square.

The given statement is 鈥淓very square is a rhombus鈥�

The given additional statement is 鈥�PQRS is a square鈥�.

Here PQRSis given that a square.

Since every square is a rhombus, therefore PQRS is a square.

Hence the conclusion is thatPQRS is a square.

The given statement is 鈥淓very square is a rhombus鈥�

The given additional statement is 鈥�GHIJis not a square鈥�.

Here GHIJis given that not a square.

Since every square is a rhombus, therefore GHIJ may or may not a rhombus.

Hence, the conclusion is not possible.
