Tiêu đề TEST 1- UNIT 5 - HS.docx ✅

d. Albert Einstein developed his theory of relativity after daydreaming about riding on a beam of light. e. These examples prove that our minds continue working on problems even when we aren't actively thinking. A. c-d-a-b-e B. b-d-c-a-e C. a-b-c-d-e D. d-a-b-c-e Question 17: a. The ballpoint pen, which became popular in the 1940s, transformed how students took notes because it was affordable, didn't leak like fountain pens, and made writing accessible to everyone. b. Blackboards became essential classroom tools in the 1800s, and they allowed teachers to share information with many students at once, which made group learning more effective. c. The internet has perhaps been the most transformative educational invention, as it connects students to unlimited information and allows learning to happen anywhere and anytime. d. The printing press, invented by Johannes Gutenberg in the 15th century, revolutionized education by making books widely available to people who previously had no access to written knowledge. e. Personal computers, which entered classrooms in the 1980s, changed how students researched topics and completed assignments, while giving them new skills for the modern world. A. d-c-a-e-b B. d-b-a-e-c C. d-e-b-a-c D. d-a-e-c-b Read the following passage about Innovation for Planetary Survival and mark the letter A, B, C or D on your answer sheet to indicate the option that best fits each of the numbered blanks from 18 to 22. Climate change represents one of humanity's greatest challenges, (18)_________. Solar panels, which convert sunlight directly into electricity, have become more affordable and efficient over the past decade. These renewable energy devices are being installed on rooftops and in large solar farms around the world, reducing our dependence on fossil fuels. Wind turbines, which harness the power of moving air, complement solar technology by generating electricity day and night. (19)_________. If these climate solutions had been implemented earlier, we might have avoided some of the environmental damage we see today. Carbon capture technologies, which remove CO₂ directly from the atmosphere, offer hope for reducing greenhouse gas concentrations. Scientists (20)_________. Electric vehicles have revolutionized transportation by eliminating tailpipe emissions while providing practical alternatives to conventional cars. What scientists have discovered is that vertical farming techniques allow food production with minimal land use and reduced water consumption, (21)_________. Working together and embracing these technologies, humanity can create a more sustainable future. The development of biodegradable plastics represents another crucial advancement in our fight against pollution. These materials, designed to break down naturally in the environment, could significantly reduce the plastic waste crisis affecting our oceans and landscapes. Smart grids (22)_________. Researchers continue to explore innovative solutions such as artificial photosynthesis and ocean cleanup systems to heal our planet. Question 18: A. while researchers continue investigating potential solutions through international collaboration efforts B. yet economic policies remain insufficient for managing sustainable urban development projects
