A Heap is a specialized tree-based data structure that satisfies the heap property. Heaps are commonly used to implement priority queues, where elements with higher priority are dequeued before those with lower priority. The key feature of a heap is that it allows constant-time access to the minimum (or maximum) element, making it efficient for applications where quick access to extreme values is required. Heaps are often used in algorithms like Dijkstra's Algorithm and Prim's Algorithm.

The correct answer is "Eisenhower Matrix." The Eisenhower Matrix, also known as the Urgent-Important Matrix, helps individuals prioritize tasks based on their urgency and importance. By categorizing tasks into quadrants, users can identify activities that require immediate attention and those that can be delegated or eliminated. This systematic approach to time management enhances productivity and facilitates better decision-making.

Stored procedures in databases offer advantages such as facilitating modular programming, where complex tasks can be broken down into smaller, manageable units. They also enhance security by controlling access to data. However, they may increase network traffic due to the transfer of data between the database and application, and debugging stored procedures can be challenging compared to debugging application code.

Effective eye contact during a presentation signifies engagement. It shows that the speaker is actively connecting with the audience, maintaining their attention, and conveying confidence in the message being delivered. Eye contact establishes a sense of rapport and trust between the presenter and the audience, making the presentation more impactful and persuasive.

Text message is not typically considered a common form of written communication in a professional setting. While emails, memoranda, reports, and presentations are commonly used for professional communication due to their formal nature and ability to convey detailed information, text messages are more informal and often used for quick, casual communication. In a professional setting, written communication is generally expected to be more structured and comprehensive.

Sharing success stories demonstrates tangible benefits of team building and helps skeptical team members see its potential impact on organizational goals, fostering buy-in and enthusiasm for future activities.

Empathy refers to the ability to understand and share the feelings of others. It involves being able to put oneself in another person's shoes and genuinely connect with their emotional experience.

Compile-time errors are identified by the compiler during the compilation process, while runtime errors occur during the execution of the program. Compile-time errors are generally easier to locate and fix since they are caught before the program runs. Runtime errors can be more challenging to debug as they occur during program execution.

Non-verbal cues such as eye contact can provide valuable insights into a speaker's emotions and intentions. For instance, maintaining eye contact can indicate sincerity and engagement, while avoiding it may suggest discomfort or dishonesty. Thus, by paying attention to non-verbal cues, listeners can gain a deeper understanding of the speaker's message beyond mere words.

In a multi-user operating system environment, concurrent access to the same file can lead to data integrity issues and conflicts. Implementing a file locking mechanism allows processes to gain exclusive access to the file while preventing others from modifying it simultaneously. This ensures data integrity by serializing access to the file.

Active listening and empathy are crucial components in effectively handling customer complaints. When you listen actively, you demonstrate to the customer that their concerns are valued, which can help de-escalate the situation. Empathy allows you to understand the customer's perspective and respond appropriately, leading to a more satisfactory resolution.

Option 3 suggests developing a comprehensive strategy to address both the identified risks and opportunities. This approach involves careful planning and mitigation measures to minimize potential risks while maximizing the benefits of market expansion.
