A city council wants to identify all "beautiful parks" for a renovation grant. Why is this instruction not suitable for creating a mathematical set of parks? (a) Because the number of parks is finite. (b) Because the criterion "beautiful" is subjective and not well-defined. (c) Because parks are physical locations. (d) Because the city might not have any parks. 2. Let A be the set of all four-sided polygons (quadrilaterals) and B be the set of all rhombuses. Which statement accurately describes their relationship in geometry? (a) A and B are equal sets (A=B). (b) A is a proper subset of B(A⊂B and A≠B). (c) B is a proper subset of A(B⊂A and B≠A). (d) A and B are disjoint sets. 3. An engineer plots the exact path of a single, continuous weld seam on a large metal plate. If the set S represents all the infinite points that form this continuous line, the set S is: (a) An empty set (b) A finite set (c) An infinite set (d) A singleton set 4. A food delivery app has filters for its restaurant listings. A={ Restaurants that are 'Pure Veg' } B={ Restaurants that offer 'Chinese' cuisine } A user wants to find a 'Pure Veg' restaurant that serves 'Chinese'. Which set operation represents the user's search result? (a) A∪B (b) A∩B (c) A-B (d) B^' 5. Let U be the set of all products on an e-commerce website. Let F be the set of products eligible for "Free Delivery". The set F^' (complement of F) represents: (a) The set of all products that have a delivery charge. (b) The set of all items not sold on the website. (c) The set of all products with "Free Delivery". (d) An empty set, because all products have a delivery status. 6. In a computer network, let S be the set of all servers and W be the set of all workstations. No machine is both a server and a workstation. If S∩W=ϕ, what does this signify? (a) The network has no servers. (b) Every server is also a workstation. (c) The roles of server and workstation are mutually exclusive. (d) The network only contains servers and workstations. 7. An engineer is designing a circuit. The voltage v must be a real number that satisfies the equation V^2+12=7. The set of all possible values for v is: (a) {√5,-√5} (b) {5,-5} (c) {5} (d) ϕ (The Empty Set), as V^2 cannot be negative. 8. A biologist studies animal habitats. Let F be the set of all animals that live in forests, and A be the set of all amphibians. If A⊂F, what is the most logical conclusion? (a) Every forest-dwelling animal is an amphibian. (b) All known amphibians in this study live in forests. (c) No amphibians live in forests. (d) The group of amphibians is the same as the group of forest animals. 9. A music streaming app has two toggles for a playlist: "Explicit Content" (Set A) and "Downloaded" (Set B). A user wants to listen to only downloaded songs that are NOT explicit. The resulting playlist is represented by which set? (a) A∩B (b) A∪B (c) A-B (d) B-A 10. A manufacturing robot is programmed with two rules. Rule 1 (Set A): It can only handle parts whose weight w is a factor of 24 kg . Rule 2 (Set B ): It can only handle parts whose weight w is a multiple of 4 kg . Which of the following part weights can the robot handle? (a) 6 kg (b) 10 kg (c) 12 kg (d) 16 kg Important links Answer of this worksheet - https://www.teachoo.com/25604/5368/MCQ---Worksheet-1/category/Teachoo-Questions---MCQs/ Full Chapter with Explanation, Activity, Worksheets and more – https://www.teachoo.com/subjects/cbse-maths/class-11th/ch1-11th-sets/ Maths Class 11 - https://www.teachoo.com/subjects/cbse-maths/class-11th/ For more worksheets, ad-free videos and Sample Papers – subscribe to Teachoo Black here - https://www.teachoo.com/black/   Answer Key to MCQ Worksheet 1 (b) Because the criterion "beautiful" is subjective and not well-defined.
