Directions: Read the given passage carefully and answer the questions that follow by selecting the most appropriate option.

Helicopters are $\underline{very}$ different from airplanes. They can do three things that airplanes cannot do. First, when airplanes move upward, they must also move forward, but helicopters can move straight up without moving ahead. Second, helicopters can fly backward, which airplanes cannot do. Third, helicopters can use their rotors to $\underline{hover} in the air, which is impossible for airplanes. Helicopters can $\underline{perform}$ actions that airplanes cannot, they are used for different tasks. Since helicopters can take off without moving forward, they do not need a runway for takeoff. They are used in $\underline{congested}$ areas where there is no room for airplanes or in isolated areas, which do not have airports. Because they can hover, they are used on fire-fighting missions to drop water on fires. They are used in logging operations to lift trees out of forests. Helicopters are used as air ambulances to airlift patients out of situations, which are difficult to reach by conventional ambulances. The police use helicopters to follow suspects on the ground or to search for cars on the ground. Of course, helicopters have military uses because of their design and capabilities.

Why is a helicopter used as an ambulance ?

Accepted Answer

Here is a detailed explanation for the given question:

**Justification for Option 3 (Correct Answer):**

*   The passage explicitly states: "Helicopters are used as air ambulances to airlift patients out of situations, which are difficult to reach by conventional ambulances."
*   The phrase "difficult to reach by conventional ambulances" directly corresponds to "inaccessible places." Helicopters, with their unique ability to take off vertically and hover, can access locations that ground-based ambulances cannot, such as remote areas, mountainous terrain, or accident sites without road access. Therefore, the ability to reach inaccessible places easily is the precise reason given in the text for their use as ambulances.

**Explanation for Incorrect Options:**

*   **Option 1: It crosses all difficulties of traffic**
    *   While helicopters can indeed bypass traffic, the passage does not state this as the primary reason for their use *as an ambulance*. The passage mentions helicopters being used in "congested areas" because they don't need a runway, but the specific reason for their ambulance role is linked to reaching "difficult to reach" situations, which is a broader concept than just traffic. Traffic is one type of difficulty, but "inaccessible places" is a more accurate and comprehensive reason provided in the text for ambulance use.

*   **Option 2: Its movement can be manoeuvred easily**
    *   The passage highlights several unique capabilities of helicopters, such as moving straight up, flying backward, and hovering, which collectively demonstrate their high maneuverability. However, the passage does not directly state that "easy maneuverability" is the reason for their use as an ambulance. Instead, it states that they are used to reach "situations, which are difficult to reach by conventional ambulances." While maneuverability contributes to reaching such places, Option 3 is a more direct and specific restatement of the reason provided in the text for their ambulance role.

*   **Option 4: It can fire fight**
    *   The passage clearly states that helicopters are used "on fire-fighting missions to drop water on fires." This is a distinct application of helicopters, separate from their role as air ambulances. The text provides a different reason for their use in fire-fighting (because they can hover) than for their use as ambulances. Therefore, this option describes another capability of helicopters but not the reason for their use as an ambulance.
