Answer 1

(i) {2, 3, 4} $\subset$ {1, 2, 3, 4, 5}

(ii) {a, b, c} $\subset ̸$ {b, c, d}

(iii) {x: x is a student of Class XI of your school}

$\subset$ {x : x student of your school}

(iv) {x : x is a circle in the plane} $\subset ̸$ {x : x is a circle in the same plane with radius 1 unit}

(v) {x : x is a triangle in a plane} $\subset ̸$ {x : x is a rectangle in the plane}

(vi) {x : x is an equilateral triangle in a plane} $\subset$ {x : x is a triangle in the same plane}

(vii) {x : x is an even natural number} $\subset$ {x : is an integer}
