Question

    In the question given below, a passage is given

    followed by three statements which may or may not be inferred from the passage. Select the correct combination of statements that can be inferred. The concept of using Earth’s internal heat to generate electricity is attractively simple. Temperatures in the planet’s core approach those found at the surface of the Sun, and the heat leaks outward. In places this geothermal energy emerges at Earth’s surface as molten lava, steaming vents, and hot springs. More often, however, it remains trapped in deep sediments and rock. I. Sediments present deep into the ground prevent geothermal energy from coming to Earth’s surface. II. The deeper we go into the earth, the higher the temperature will be. III. The cores of planets and stars can have nearly the same temperatures.
    A Only II & III Correct Answer Incorrect Answer
    B Only I Correct Answer Incorrect Answer
    C Only I & III Correct Answer Incorrect Answer
    D Only I & II Correct Answer Incorrect Answer
    E All I, II & III Correct Answer Incorrect Answer

    Solution

    Option 4 is the right answer. Both I and II can be inferred from the para. The para tells us how geothermal energy, which shows up at Earth’s surface as steaming vents and hot springs at some places, is prevented from reaching the surface by deep sediments and rocks. I follows. It also tells us how Earth’s core is very hot and how some of the heat comes outwards (towards the surface). II follows. III cannot be inferred as the passage does not talk about the core of the Sun.
