If you took the Logical Reasoning exam for the SESC DF position of Management Support Assistant, administered by Instituto IBEST in 2026, this video provides a complete, detailed, and 100% commented answer key for questions 11 to 15. Here at Matemática Bruta, you can follow the step-by-step solution, understanding the reasoning behind each item and how IBEST typically tests: negation with quantifiers ("all/some"), anagrams, sets/Venn diagrams, matrix mean, and logical propositions with conditional, biconditional, and "or". In practice, it's the commented answer key for the Logical Reasoning section of the SESC DF 2026 exam (IBEST). 💚 Support Brutal Math Become a member and get exclusive benefits 👉    / @matematicabruta   ❤️ Subscribe and activate the 🔔 https://www.youtube.com/@matematicabr... ⏱ VIDEO INDEX (fill in the times after uploading the video) 00:00 Introduction 01:09 Question 11 – Negation with quantifiers 03:07 Question 12 – Anagrams with restriction (consonant) 06:59 Question 13 – Sets: two walks (Venn) and none 10:25 Question 14 – Mean of matrix elements 12:13 Question 15 – True propositions and identification of false propositions 📌 Questions solved in this video (complete statements, no multiple-choice options) QUESTION 11 Choose the option that presents the negation of the proposition "All sunflowers are yellow".
