Flashcard Examples for Concurso Correios
Portuguese
- Front: "When do you use crase before the word 'casa'?"
- Back: "Use crase when 'casa' is modified (specified): 'Voltei a casa de meus pais.' → 'Voltei a casa.' (no modifier = no crase). 'Fui a casa da vizinha.' (modified = use crase: 'Fui a casa da vizinha.') Wait -- actually if 'casa' means 'lar' and is unmodified, no crase. If modified, use crase if feminine article applies."
Correios Knowledge
- Front: "What is the difference between SEDEX and PAC?"
- Back: "SEDEX: Express delivery (1-3 business days), more expensive, tracking included, insurance available. PAC: Economy delivery (5-10+ business days), cheaper, tracking available, good for non-urgent packages."
Mathematics
- Front: "A package weighs 2.5 kg. If the rate is R$3.80/kg, how much does shipping cost?"
- Back: "2.5 x R$3.80 = R$9.50."
IT
- Front: "What is phishing?"
- Back: "Phishing is a cyberattack where attackers send fake emails or messages impersonating legitimate companies to trick users into revealing personal data (passwords, credit card numbers). Prevention: verify sender, don't click suspicious links, check URLs."
