Read this excerpt from "A Student's Guide to Global Climate Change."
Based on the excerpt, what conclusion can be drawn
about protective barriers?
Climate change poses risks for cities near the ocean.
Places like Miami; New York City, New Orleans; and
Venice, Italy, could flood more often or more severely if
sea level continues to rise. If that happens, many people
will lose their homes and businesses,
They should be built along coastal communities.
O They should be built where natural barriers are
missing.
O They are the same as natural barriers.
They are usually unnecessary along shorelines.
What can people do about it?
Coastal cities can prepare for climate change by
protecting or restoring natural shoreline buffers like sand
dunes and wetlands, improving storm drainage systems,
and building protective barriers where necessary.

Urgent will give brainliest to the first correct answermeee major test (1) wayne gretzky once said, “you’ll always miss 100% of the shots you don’t take.” (2) life would be dull and boring if no one took risks. (3) many people have accomplished astonishing things because they took a risk. (4) in other words, my mind is set on the belief that it’s worthwhile to take risks. (5) one reason to take a risk is that you can learn from your mistakes, and that allows you to accomplish your goal correctly the next time. (6) for instance, the wright brothers dreamed of being able to fly. (7) they decided to invent the airplane. (8) certainly, they weren’t able to construct it perfectly the first time, so they took a risk and kept trying until they finally got it right. (9) because they learned from their mistakes, that encouraged them to continue to work hard and succeed at inventing one of todays most convenient inventions, the airplane. (10) another reason to take risks is that you can form relationships. (11) a good example of this is the play, “novio boy” by gary soto. (12) rudy, the main character, asks patricia, his crush, to go on a date with him. (13) he took a risk because she is older than him, and rudy wasn’t sure of what she would say. (14) fortunately, patricia agreed to go out with him. (15) therefore, taking risks can be positive and you form relationships. (16) in conclusion, you never know what you are capable of until you take a risk. (17) there could be many motives that could make you want to take a risk. (18) the result could turn out to be either good or bad. (19) despite the consequences, you never know what you could achieve before you take the risk. the word "before" does not appropriately connect the two clauses in sentence 19. which word should replace "before"? unless although since after
