Read the following article and answer the question. Article: About 97% of the world's water is salty and is found in our oceans and seas. But, as we can't drink seawater, how can it be important? Every part of our seas and oceans contains an amazing number of animals and fish that live at different ocean depths. Most of the different species of animals and fish depend on simple plants for their food. These simple plants called algae drift near the surface of the ocean and use sunlight to turn carbon dioxide and water into food and oxygen. In fact, algae produce over half of the oxygen people breathe. How important seawater is! Each plant or animal in our seas and oceans is an important link in a food chain. The algae are eaten in large amounts by microscopic animals, which are in turn consumed by larger animals. These food chains are delicately balanced. The bad news about the food chains in the oceans is that they are under threat because of man. People once thought that the oceans were so big that it didn't matter if we dumped rubbish into them or caught huge quantities of fish and whales for food. But we now know this is not true and fish stocks in the oceans have started to drop. Thankfully, the world is taking steps to protect the future of our oceans by introducing international agreements to protect marine habitats. Most countries have introduced fishing restrictions to protect fish stocks in the oceans and new techniques are being pioneered to cope with pollution. Finally, the importance of protecting oceans is being made known to more people. This is just the beginning of a long process to protect the oceans for our future. We depend on the oceans for fish which are an important part of the human diet. How important seawater is! Question: People used to think that the rubbish thrown into the sea _ . Answer:
OPTIONS:
- wouldn't harm the fish in the sea
- would change the balance of the food chain
- would be broken down in the sea
- wouldn't do much harm to the sea

Answer: wouldn't do much harm to the sea

Read the following article and answer the question. Article: Next time a customer comes to your office, offer him a cup of coffee.And when you're doing your holiday shopping online, make sure you're holding a large glass of iced tea.The physical sensation of warmth encourages emotional warmth, while a cold drink in hand prevents you from making unwise decisions--those are the practical lesson drawn from recent research by psychologist John Bargh. Psychologists have known that one person's perception of another's "warmth" powerfully determines social relationships.Judging someone to be either "warm" or "cold" is a primary consideration, even trumping evidence that a "cold" person may be more capable.Much of this is rooted in early childhood experiences, Bargh argues, when babies' conceptual sense of the world around them is shaped by physical sensations, particularly warmth and coldness.Classic studies by Harry Harlow, published in 1958, showed monkeys preferred to stay close to a cloth "mother" rather than one made of wire, even when the wire "mother" carried a food bottle.Harlow's work and later studies have led psychologists to stress the need for warm physical contact from caregivers to help young children grow into healthy adults with normal social skills. Feelings of "warmth" and "coldness" in social judgments appear to be universal.Although no worldwide study has been done, Bargh says that describing people as "warm" or "cold" is common to many cultures, and studies have found those perceptions influence judgment in dozens of countries. To test the relationship between physical and psychological warmth, Bargh conducted an experiment which involved 41 college students.A research assistant who was unaware of the study's hypotheses handed the students either a hot cup of coffee or a cold drink to hold while the researcher filled out a short information form: The drink was then handed back.After that, the students were asked to _ the personality of "Person A" based on a particular description.Those who had briefly held the warm drink regarded...

Read the following article and answer the question. Article: It was only 5 o'clock in the morning. The house was quiet and Tim' s mother was still asleep. Only the sound of the big freezer broke the quiet. He'd dreamt of the cave last night. The purring of the freezer had been the sea. Tim pulled on a sweater and put some apples into his schoolbag. It was too early for breakfast. He' d eat after he' d been through the cave, sitting on the rocks and staring at the sea. He wished he had a proper pack. His schoolbag would have to do. What else? Sandwiches-but his mother might wake up if he started pulling out bread for sandwiches, she'd want to know why he had to leave so early. He settled for some biscuits, and left a note stuck to the table: Gone to Michael's. Back tonight, Tim. The sky was high and soft and light outside, though the sun still wasn't up. Even the highway up the hill was quiet as he made his way down the street. The wind from the sea was fresh and sweet. The sand hills still breathed heat from yesterday's sun, though the top of the sand was cool. He ran down to the beach impatiently, but there was no one, just dry sand dancing in the early wind and seabirds marching up and down watching the waves. The light changed suddenly. The first rays of sunlight stretched across the sea. The sun was pushing its way over the edge of the world. Over the first rocks, along to the point, Tim glanced back. The beach was still empty. The sun sailed higher in the sky. He could see the cave now, even darker in the morning light. The sand turned silver then dark gold as the water flowed away from it. He had to force himself to go closer. Why was it so much more mysterious now? But it would be silly to go back now after so much trouble. He needn't go in all the way... Question: In the story, Tim's mood changed from _ . Answer:
OPTIONS:
- loneliness to craziness
- anxiousness to excitement
- eagerness to nervousness
- helplessness to happiness

Answer:
eagerness to nervousness
