Homework #2Total 20 pointsNinth Grade Total 10%Present this homework during week 13 (L- 30 de abril al D- 6 de mayo) It must bepresented formally and individually on the exact date.Objective: Applying basic elements of grammar in new contexts, with 80% accuracyContent: CAUSES, EFFECTS, AND PREVENTION OF ENVIRONMENTAL POLLUTIONInstructions:1. Read the information about: Costa Rican bridges vulnerable toearthquakes.2. Write a TWENTY line paragraph about the reading.3. Make five information questions about your paragraph (what, how, why,etc.) And give five long answers to these information questions.In 1991, Costa Rica suffered its strongest earthquake to date. It was a sunny and calm Aprilafternoon when the earth started to shake. Panic ensued, and when things stopped moving, manybuildings, roads and bridges were left with cracks and structural damage.Since then, more than 300 kilometers of roads have been repaired, and the government spent nearly₡22 billion ($43 million) to fix damages.But the country’s bridges haven’t fared so well.One bridge that remains damaged from the quake 20 years ago spans the Chirripó River on Route 32to the Caribbean coast, between Siquirres and Limón. If the bridge were to fail, the port city of Limónwould be disconnected from the rest of the country. Supports on the bridge fell out of alignment, itlacks paint, rust is eating away parts of it, and one of the expansion joints is making the pavementcrack on the bridge’s surface.The Chirripó River Bridge is one of many Costa Rican bridges in bad condition. The government stillconsiders it safe, but its structure has so many problems that another strong earthquake couldrender it useless.“Bridges should get inspected every two years, since only those inspections will determine themaintenance work they need,” said Rolando Castillo, an engineer and head of the bridge departmentat the University of Costa Rica’s National Laboratory of Materials and Structural Models (Lanamme).According to Castillo, Costa Rica has very few bridges that have been built to resist the force ofearthquakes. Before 1971, no proper set of standards existed to establish best practices in terms ofbridge construction in seismic zones. It wasn’t until the 1971 San Fernando Earthquake, which led tomajor bridges malfunctions inthe U.S., that engineers started worrying about seismic-resistant bridge construction.Costa Rica’s most infamous bridge, the Virilla River Bridge on the General Cañas Highway, known asthe “Platina” bridge for its shoddy construction, was not seismically designed. It was built to support24-ton trucks, while today’s bridges are designed for 40-ton trucks.6
