The language of the text is JavaScript. Here is the step by step solution:

Step 1: Create a class called Person with properties name, age, and gender.

```javascript
class Person {
constructor(name, age, gender) {
this.name = name;
this.age = age;
this.gender = gender;
}
}
```

Step 2: Add a method speak() to the Person class.

```javascript
class Person {
constructor(name, age, gender) {
this.name = name;
this.age = age;
this.gender = gender;
}

speak() {
console.log(`Hello, my name is ${this.name} and I am ${this.age} years old.`);
}
}
```

Step 3: Create a class called Student with properties person, major, and gpa.

```javascript
class Student {
constructor(person, major, gpa) {
this.person = person;
this.major = major;
this.gpa = gpa;
}
}
```

Step 4: Add methods study() and speak() to the Student class.

```javascript
class Student {
constructor(person, major, gpa) {
this.person = person;
this.major = major;
this.gpa = gpa;
}

study() {
console.log(`I am studying ${this.major} and my GPA is ${this.gpa}.`);
}

speak() {
console.log(`Hello, my name is ${this.person.name} and I am ${this.person.age} years old. I am also a student studying ${this.major}.`);
}
}
```

Step 5: Create instances of Person and Student and call their methods.

```javascript
const person1 = new Person("John", 20, "M");
person1.speak();

const stud1 = new Student(person1, "CS", 9);
stud1.speak();
stud1.study();
```

This will output:

```
Hello, my name is John and I am 20 years old.
Hello, my name is John and I am 20 years old. I am also a student studying CS.
I am studying CS and my GPA is 9.
```
