You define the Pet class as follows:
class Pet {
constructor(name, breed) {
this.name = name;
this.breed = breed;
this.show = function() {
var text = " < p > Your pet ' s name is " + name + " . The pet ' s breed is " + breed + " . < /p > " ; return text;
};
}
}
You need to derive a Dog class from the Pet class.
Complete the code by selecting the correct option from each drop-down list.
Note: You will receive partial credit for each correct selection.

Explanation:
First blank: class Dog extends Pet {
Second blank: super(name, breed);
The correct syntax for deriving one JavaScript class from another is extends, so the derived class declaration must be class Dog extends Pet {. This creates Dog as a subclass of Pet, allowing Dog instances to inherit members defined by the Pet constructor, including name, breed, and the show() function assigned inside the parent constructor. Inside a derived class constructor, super() must be called before using this. The call super (name, breed); invokes the parent Pet constructor and passes the values required to initialize the inherited name and breed properties. Pet(name, breed); is incorrect because a class constructor cannot be invoked like a normal function. Pet.constructor(name, breed); is also incorrect because it does not call the parent constructor for the current instance. After super() runs, the Dog constructor can safely assign subclass-specific properties such as price and gender.

Move the appropriate attributes from the list on the left to the correct descriptions on the right. You may use each attribute once, more than once, or not at all.
Note: You will receive partial credit for each correct match.

Explanation:
pattern # Provides a way to set a regular expression that the value must match placeholder # Provides a way to set default text that displays until focus is placed in an element required # Provides a way to set form elements as mandatory multiple # Provides a way to allow more than one file or email address in a single input The correct matches are based on standard HTML5 form validation and input-attribute behavior. The pattern attribute defines a regular expression that the input value must satisfy before the form can be submitted successfully. It is commonly used for structured values such as phone numbers, codes, postal formats, or custom identifiers. The placeholder attribute supplies short hint text inside an input field, helping the user understand the expected value before entering data. The required attribute makes a form control mandatory; if the field is empty, constraint validation prevents successful submission. The multiple attribute allows a single input to accept more than one value, specifically for controls such as input type= " file " and input type= " email " , where users may upload multiple files or enter multiple email addresses. The maxlength attribute is not used in these matches because it limits the maximum number of characters that can be entered, but none of the listed descriptions asks for character-length restriction.

You are given the design for an app. The project manager asks you to outline the steps you must take to release and maintain the app.
Move each step from the list on the left to its correct sequence in the application lifecycle on the right.
Note: You will receive partial credit for each correct response.

Explanation:
Determine requirements # Develop code # Test the app
#
Monitor performance # Deploy the app
The correct application lifecycle sequence begins with Determine requirements because the team must first define what the app must accomplish, who will use it, and which functional and technical expectations must be satisfied. Since the question states that the design is already provided, the next implementation step is Develop code, where the HTML, CSS, JavaScript, assets, APIs, and app logic are created according to the approved design and requirements. After development, the app must be validated through Test the app.
Testing confirms that the app works correctly, meets requirements, handles user input properly, and does not contain functional defects that would block release. Once testing is complete, the app can be released through Deploy the app, which publishes it to the target environment or makes it available to users. The final operational stage is Monitor performance, where the released app is observed, maintained, updated, and improved based on performance, reliability, defects, and user behavior.
