1.
Passage:
The human circulatory system is a complex network of blood vessels that transport oxygen, nutrients, and
waste products throughout the body. The heart acts as the central pump, ensuring that blood reaches every
cell. Arteries carry oxygen-rich blood away from the heart, while veins return oxygen-poor blood back to
the heart. Capillaries facilitate the exchange of materials between blood and tissues.
Question:
What is the primary function of capillaries in the circulatory system?
A. Pump blood throughout the body
B. Carry oxygen-rich blood away from the heart
,C. Facilitate exchange between blood and tissues
D. Return oxygen-poor blood to the heart
Correct Answer: C. Facilitate exchange between blood and tissues
Rationale:
Capillaries are tiny blood vessels where oxygen, nutrients, and waste products are exchanged between
blood and tissues. Option A describes the heart’s role, B describes arteries, and D describes veins.
2.
Passage:
Climate change has led to rising global temperatures, melting polar ice, and shifting weather patterns.
Scientists attribute these changes primarily to increased greenhouse gas emissions from human activities
such as burning fossil fuels and deforestation.
Question:
According to the passage, what is the main cause of climate change?
A. Natural weather cycles
B. Greenhouse gas emissions from human activities
C. Solar radiation fluctuations
D. Volcanic eruptions
,Correct Answer: B. Greenhouse gas emissions from human activities
Rationale:
The passage explicitly states that human activities like burning fossil fuels and deforestation increase
greenhouse gas emissions, causing climate change. The other options are not mentioned as primary
causes.
3.
Passage:
Photosynthesis is the process by which green plants convert sunlight, carbon dioxide, and water into
glucose and oxygen. This process occurs in chloroplasts, which contain the pigment chlorophyll.
Question:
Where does photosynthesis take place in plant cells?
A. Mitochondria
B. Nucleus
C. Chloroplasts
D. Cell wall
Correct Answer: C. Chloroplasts
Rationale:
, The passage states that photosynthesis occurs in chloroplasts, which contain chlorophyll. Mitochondria
are involved in cellular respiration, the nucleus stores genetic material, and the cell wall provides
structural support.
4.
Passage:
The immune system defends the body against pathogens such as bacteria and viruses. White blood cells,
or leukocytes, play a key role by identifying and destroying these invaders.
Question:
Which cells are primarily responsible for destroying pathogens?
A. Red blood cells
B. Platelets
C. White blood cells
D. Stem cells
Correct Answer: C. White blood cells
Rationale:
The passage identifies white blood cells (leukocytes) as the cells that identify and destroy pathogens. Red
blood cells transport oxygen, platelets aid in clotting, and stem cells produce other blood cells.
