As you need LSAT, Logical Reasoning section quiz questions, here I will help you for that so that you can easily solve them. Here are some quiz questions Level 1 : super basic diagramming for if-then statements- make a diagram for the original statement and the contrapositive. 1. If you are a wild penguin, then you live in the southern hemisphere. 2. If you are a penguin, then you cannot fly. Level 2: diagramming statements with ‘only if”, ‘must’, and ‘required’- make a diagram for the original statement. 3. Only if you are a wizard can you use a wand. 4. You must be a hardened criminal to commit burglary. 5. You are required to take a test to pass driving school. Level 3: diagramming statement with ‘unless’, ‘without’, and ‘except’- make a diagram for the original statement and the contrapositive. 6. You can’t be a pilot unless you have good vision. 7. You are nothing without somebody to love. 8. Except for mermaids, humans cannot breathe under water. 9. If you are bitten by a radioad0jctive spider, then you are super strong and can make webs. 10. If you took the brown acid, then you are freaking out or believe you are a canary. 11. If you are a penguin then you cannot fly. If you cannot fly then you are a mainly terrestrial species. Answer choices: a. If you are a mainly terrestrial species then you cannot fly. b. If you are a penguin then you are mainly a terrestrial species. c. If you are not a penguin then you can fly. 12. If you found unobtainum, then you are mining on Pandora. You are are actually mining on one of the moon’s other than Pandora that surround the planet Polythemus. Answer choices: a. You found unobtainium. b. You did not find unobtainum. c. You found something other than obtainium. 13. There is some debate as to whether great-crested grebes are common in Swansea, but it is known that most grebes live in North Savoy and some grebes live within a mile of a lake. Also, most grebes inhabit boggy areas. Choose the inference that can be properly made from the premises: a. Some grebes in Swansea live within a mile of a lake. b. Some grebes in North Savoy live within a mile of a lake. c. Some grebes in North Savoy inhabit boggy areas. 14. Most unobtainum is only found in the found in the lush jungle covered areas of Pandora. Some of the miners are out seeking unobtainum in the arid regions, and some of them located unobtainium. Overall, a large quantity of unobtainum was discovered and mined on Pandora in the last month. List any of the following which could be true. a. All of the large quantity of unobtainium from last month was discovered and mined in the arid regions of Pandora. b. Most of the large quantity of unobtainium from last month was discovered in the jungle regions of Pandora. c. None of the large quantity of unobtainium from last month was discovered in the jungle regions of Pandora. d. Not all of the large quantity of unobtainum was discovered in the arid regions of Pandora. e. All of the unobtainium mined in Pandora last month was from the jungle regions of Pandora. Answers key: 1. If you are a wild penguin, then you live in the southern hemisphere. Diagram: WP —–> SH Contrapositive: Not SH —-> Not WP Alternative Diagram of contrapositive: SH ——> WP 2. If you are a penguin, then you cannot fly. Diagram: P —–> Not F Alternative diagram: P —–> F (from here on out we are going to stick with the slash style of diagramming). 3. Only if you are a wizard can you use a wand. Diagram: UWnd ——> Wiz 4. You must be a hardened criminal to commit burglary. Diagram: CB —–> HC 5. You are required to take a test to pass driving school. Diagram: PDS ——> TT 6. You can’t be a pilot unless you have good vision. Diagram: P —–> GV (could be phrased as an if-then statement: if you are a pilot then you have good vision) Contrapostive GV ——> P Tips: ‘unless’, ‘without’, and ‘except’ can be a little tricky. If you can’t do it intuitively, here is the mechanical approach: take whatever comes after those phrases and put it in the necessary condition spot. The rest is negated then put in the sufficient condition spot. 7. You are nothing without somebody to love. N —–> STL (could be phrased as an if-then statement: If you are not nothing then you have somebody to love) STL —–> N 8. Except for mermaids, humans cannot breathe under water. HBW ——> M (could be phrased as an if-then statement: If you are a human that breathes under water, then you are a mermaid) M ——-> HBW 9. If you are bitten by a radioactive spider, then you are super strong and can make webs. Contrapositive: If you are not super strong or cannot make webs, then you were not bitten by a radioactive spider. Diagram: SS or MW ——–> BRS 10. If you took the brown acid, then you are freaking out or believe you are a canary. Contrapositive: If you don’t believe you are and canary and you are not freaking out, then you did not take the brown acid. Diagram: BC and FO ——–> TBA Tip: Note that these ‘and’ switches to ‘or’ in the contrapostive and vice versa. This also the case with making contrapositives with the conjunctions ‘and’ and ‘or’. 11. If you are a penguin then you cannot fly. If you cannot fly then you are a mainly terrestrial species. Correct answer: b. 12. If you found unobtainum, then you are mining on Pandora. You are are actually mining on one of the moon’s other than Pandora that surround the planet Polythemus. Correct answer: b |
