Transcript:

Dengue disease is carried and spread by mosquitos. The most famous of these is the yellow-fever mosquito, or Aedes aegypti, to give it its scientific name. The mosquito becomes infected if it bites an infected person or monkey during the first three days of illness. After the disease has incubated in the mosquito's body for nine days, the mosquito can then transmit the disease by injecting tiny droplets of saliva into other people or monkeys.
Symptoms of the disease include fever and excruciating joint pain. That's why it's sometimes called 'breakbone fever'. One way of stopping the disease from spreading is to prevent the mosquitos from accessing their breeding grounds. Insecticides can be sprayed during outbreaks and applied to water-storage areas.

* Click on the correct answer

The dengue mosquito spreads yellow fever by biting people and monkeys. A victim of the disease has a fever for three days, usually followed by aches and pains in their body. The disease can only be completely eradicated by wiping out the mosquitos. Mosquitos transfer Dengue disease from people in the early stages of the illness to other individuals, who then experience extreme discomfort, especially in their bones. In order to limit the disease, the mosquitos need to be prevented from laying eggs. One well-known disease spread by mosquitos is Dengue disease. Once a person has the disease they suffer from high temperatures and hysteria. The only method to stamp out the disease is by killing the mosquitos using chemicals, which can be added to water supplies. Dengue disease is passed on by mosquito bites. If the victim spends some time in isolation their symptoms will disappear and they will no longer be carriers. To stop the disease from spreading, attempts should be made to destroy the areas where the carriers live.

Option 2: "Mosquitos transfer Dengue disease from people in the early stages of the illness to other individuals, who then experience extreme discomfort, especially in their bones. In order to limit the disease, the mosquitos need to be prevented from laying eggs."

Explanation: This option accurately summarizes the main points of the text. It correctly identifies that mosquitos transfer dengue disease from infected individuals to others, particularly during the early stages of illness. The phrase 'extreme discomfort, especially in their bones' effectively captures the essence of the symptoms described in the text, which include fever and joint pain. Furthermore, it aligns with the text's recommendation of preventing mosquitos from accessing breeding grounds as a method to limit the disease's spread.

Option 1: "The dengue mosquito spreads yellow fever by biting people and monkeys. A victim of the disease has a fever for three days, usually followed by aches and pains in their body. The disease can only be completely eradicated by wiping out the mosquitos."

Explanation: This option incorrectly states that dengue is yellow fever, which is not accurate. The text specifies that dengue disease is spread by mosquitos, particularly Aedes aegypti, but does not mention yellow fever. Additionally, it misrepresents the duration of symptoms, stating a fever lasts three days, while the text indicates symptoms include fever and joint pain without specifying a duration. The claim about complete eradication through wiping out mosquitos is also misleading, as the text suggests prevention through controlling breeding grounds rather than complete eradication.

Option 3: "One well-known disease spread by mosquitos is Dengue disease. Once a person has the disease they suffer from high temperatures and hysteria. The only method to stamp out the disease is by killing the mosquitos using chemicals, which can be added to water supplies."

Explanation: This option contains inaccuracies regarding the symptoms and methods of controlling dengue disease. While it correctly identifies dengue as a disease spread by mosquitos, it inaccurately describes symptoms as 'high temperatures and hysteria,' which does not reflect the text's mention of fever and joint pain. Additionally, the text does not suggest that chemicals can be added to water supplies as a method to stamp out the disease; instead, it emphasizes preventing mosquitos from breeding in water-storage areas.

Option 4: "Dengue disease is passed on by mosquito bites. If the victim spends some time in isolation their symptoms will disappear and they will no longer be carriers. To stop the disease from spreading, attempts should be made to destroy the areas where the carriers live."

Explanation: This option misrepresents the nature of dengue disease and its transmission. While it correctly states that dengue is passed on by mosquito bites, it inaccurately suggests that isolation will lead to symptom disappearance and that the individual will no longer be a carrier, which is not supported by the text. The text does not mention isolation as a solution. Furthermore, it emphasizes preventing mosquitos from breeding rather than destroying areas where carriers live, making this option inconsistent with the text's main ideas.
