What are two reasons it is hard to land an aircraft on an aircraft carrier? A There are control towers. B There are many decks. C The pilots are tired. D The ship is moving. E The runway is short.

## Step 1<br />The problem is asking us to identify the two main reasons why it is difficult to land an aircraft on an aircraft carrier. The options provided are:<br />A. There are control towers.<br />B. There are many decks.<br />C. The pilots are tired.<br />D. The ship is moving.<br />E. The runway is short.<br /><br />## Step 2<br />We need to consider each option and determine which ones are the most significant factors that make landing on an aircraft carrier difficult.<br /><br />## Step 3<br />Option A, "There are control towers," is not a significant factor because control towers are common in many types of airfields, not just aircraft carriers.<br /><br />## Step 4<br />Option B, "There are many decks," is also not a significant factor. While an aircraft carrier does have multiple decks, this is not a primary reason why landing is difficult.<br /><br />## Step 5<br />Option C, "The pilots are tired," is not a significant factor. While fatigue can affect a pilot's ability to land an aircraft, it is not a primary reason why landing on an aircraft carrier is difficult.<br /><br />## Step 6<br />Option D, "The ship is moving," is a significant factor. The constant movement of the aircraft carrier makes it difficult for the pilot to judge the speed and distance accurately, which is crucial for a safe landing.<br /><br />## Step 7<br />Option E, "The runway is short," is another significant factor. carrier is much shorter than a typical runway, which makes it difficult for the pilot to land the aircraft safely.
