According to the passage about the human heart, where does the right side of the heart pump blood?

Read the passage: The human heart is a muscular pump about the size of a closed fist. It is divided into four chambers: two upper chambers called atria and two lower chambers called ventricles. The right side of the heart receives blood that has travelled around the body and given up much of its oxygen, then pumps it to the lungs. There the blood picks up fresh oxygen and releases carbon dioxide. The oxygen-rich blood returns to the left side of the heart, which pumps it out to the rest of the body. Valves between the chambers open and close with every beat, making sure that blood flows in only one direction. The familiar 'lub-dub' sound heard through a stethoscope is made by these valves closing.

Correct answer B. To the lungs

Explanation

The passage states that the right side receives oxygen-poor blood from the body and then pumps it to the lungs, where it picks up fresh oxygen.

Question 01 Reading Comprehension

Which of the following is the best title for the passage about the honeybee forager’s waggle dance?

Read the passage: When a honeybee forager discovers a rich patch of flowers, she returns to the hive and performs a movement known as the waggle dance. She runs in a straight line while shaking her body, then loops back and repeats the run. The angle of the straight run, measured against the vertical surface of the comb, tells her sisters the direction of the food relative to the sun. The length of time she spends waggling indicates how far away the flowers are, with longer runs signalling greater distances. The Austrian scientist Karl von Frisch spent decades decoding this behaviour and shared a Nobel Prize in 1973 for his work. His research showed that insects can pass on surprisingly precise information without sound or words.

Correct answer C. A Dance That Gives Directions

Question 02 Reading Comprehension

According to the passage about Alexander Fleming, what did he notice around the mould on his culture plate?

Read the passage: In 1928 the Scottish scientist Alexander Fleming returned from a holiday to find that one of his culture plates of bacteria had been contaminated by a mould. Around the mould was a clear ring where the bacteria had failed to grow. Fleming realised that the mould was releasing a substance that killed the bacteria, and he named it penicillin. However, he struggled to produce the substance in large, pure amounts, and for several years his discovery attracted little attention. It was only around 1940 that a team at Oxford, led by Howard Florey and Ernst Chain, found ways to purify penicillin and test it on patients. By the end of the Second World War it was being made in large quantities and had saved many lives.

Correct answer B. A clear ring where bacteria had not grown

Question 03 Reading Comprehension

What can be inferred from the passage about Ayesha’s tailoring shop in Multan?

Read the passage: Ayesha runs a small tailoring shop in Multan. Last spring she replaced the twelve old tube lights in her workroom with LED panels, which cost her more than she had expected. Her brother told her she had wasted money. Over the following six months, however, she noticed that her monthly electricity bill had fallen steadily, even though she was working longer hours to finish wedding orders. She also no longer needed to call an electrician every few weeks to replace a flickering tube. By the end of the year Ayesha had calculated that the savings had already covered the price of the new lights. She now plans to replace the ceiling fans with energy-efficient models when she has saved enough.

Correct answer D. Her brother's view about the LED panels turned out to be mistaken.

Question 04 Reading Comprehension

In the passage about coral bleaching, what does the word ‘persists’ most nearly mean?

Read the passage: Reef-building corals live in close partnership with tiny algae that dwell inside their tissues. The algae use sunlight to make food, sharing much of it with the coral, and they also give many corals their bright colours. When sea temperatures stay unusually high for several weeks, this partnership breaks down and the coral expels the algae. Without them, the coral's tissue becomes nearly transparent, and its white limestone skeleton shows through, a process called bleaching. A bleached coral is not necessarily dead. If the water cools in time, the algae can return and the coral may recover. If the heat persists, however, the weakened coral is likely to starve or fall victim to disease.

Correct answer C. Continues
