Transcript:
How so proteins in the blood they suck help them produce the eggs they lay, so they don't use the bloodiest food for food. Both female and male mosquitoes usually nectar from plants. Tragically, mosquitoes kill more people than any other creature on earth. Their bites don't kill though, but the diseases that mosquitoes carry do millions of people die every year from malaria, dengue fever, yellow fever, and other diseases that mosquitoes carry. When mosquitoes bite people, they transmit whatever diseases they happen to be carrying. Each year, more than two million people die from mosquito carry diseases. That's a big number, huh? Unfortunately, controlling mosquitoes is difficult, since they breed and spread rapidly. They lay their eggs in stagnant water, like, urn, in swamps. So draining these areas can control them. Insecticides, you know, insect killers can also eliminate them.

Option 1: "Mosquitoes cause some problems. Sucking animal’s blood enables female mosquitoes to reproduce. Mosquitoes kill more people than any other creature on Earth and the way to control them is difficult."
Explanation: This option accurately summarizes the main points of the text. It mentions that female mosquitoes suck blood to reproduce, which is a key detail. It also highlights the significant impact mosquitoes have on human mortality, stating they kill more people than any other creature, which aligns with the text's emphasis on the dangers posed by mosquitoes. Furthermore, it notes the difficulty in controlling them, reflecting the text's discussion on the challenges of mosquito control.
Option 2: "The place that mosquitoes live is dark and mysterious and it also protects them from their predators. However, DDT, an effective way to eliminate mosquitoes, was now banned in many countries."
Explanation: This option introduces information about the habitat of mosquitoes, which is not mentioned in the text. The text does not describe their living conditions as 'dark and mysterious.' While it does mention DDT and its ban, the focus on habitat distracts from the main themes of blood-sucking and mortality rates, making this option irrelevant.
Option 3: "The best way to exterminate mosquitoes in high insects environment is the kill their eggs first. They lay their eggs in stagnant water, like in swamps. So draining these areas can control them."
Explanation: This option incorrectly emphasizes egg extermination as the best method, which is not the main focus of the text. While it does mention that mosquitoes lay eggs in stagnant water, the text primarily discusses the blood-sucking behavior and the diseases mosquitoes transmit, making this option too narrow and not representative of the overall message.
Option 4: "Mosquitoes suck blood from various animals by a long feeder in its mouth to provide them with nourishment. So to control them, DDT, an insect killer, must be used many times to be successful."
Explanation: This option correctly states that mosquitoes suck blood using a long feeder, but it misrepresents the text by suggesting that DDT must be used many times for success. The text does not specify the frequency of DDT application, and the focus on nourishment oversimplifies the text's discussion about reproduction and the dangers posed by mosquitoes, making this option incomplete.
