* Select the correct answer into all dropdown fields. You need to answer all questions before clicking verify button.

The telescope will hover in a gravitationally stable spot known as Sun-Earth Lagrange Point 2, which will allow it to stay aligned with Earth as the planet around the sun. Because JWST is primarily designed to observe infrared light, it's to keep it protected from any heat or light that could out the faint signals of distant stars and planets. With the sunshield, it should only reach a maximum of 185 degrees Fahrenheit on the side exposed to solar rays; the opposite side, where the telescope's mirrors, detectors, and other instruments live, will remain at a chilly -388 degrees Fahrenheit. The gravitational properties of the Lagrange Point ensure that JWST won't flip around and fry its sensors while the solar panels and computers freeze. JWST should be ready to begin its primary scientific mission in roughly six months. The $10 billion telescope is intended to last at least five years once its mission begins, and carries enough propellant to operate for a decade.

Result:

A.I. Explanation:

Correct answer: orbits
Explanation: The verb 'orbits' correctly describes the action of the planet moving in a circular or elliptical path around the sun, fitting grammatically in the present tense and contextually in relation to celestial mechanics.
Meaning: 'Orbits' means to move in a curved path around a star, planet, or moon, specifically referring to the Earth's movement around the sun in this context.
Wrong options:
emits: Emits means to release or discharge, which does not describe the movement of the planet around the sun.
runs: Runs implies a continuous operation or function, which is not applicable to the movement of a planet in this context.
moves: Moves is too vague and does not specifically convey the precise nature of the planet's path around the sun.
Correct answer: crucial
Explanation: The adjective 'crucial' indicates the importance of keeping the telescope protected, aligning well with the context of ensuring its functionality and effectiveness in observing infrared light.
Meaning: 'Crucial' means extremely important or essential, highlighting the necessity of protection for the telescope's operation.
Wrong options:
vain: Vain suggests a lack of success or worth, which contradicts the importance implied in the context.
staggering: Staggering means astonishing or overwhelming, which does not fit the context of necessity for protection.
rational: Rational refers to being logical or reasonable, which does not convey the urgency or importance needed in this context.
Correct answer: drown
Explanation: The verb 'drown' effectively conveys the idea of overwhelming or obscuring the faint signals, fitting grammatically and contextually as it relates to the interference with the telescope's observations.
Meaning: 'Drown' means to overwhelm or obscure, particularly in the context of signals being lost amidst stronger influences like heat or light.
Wrong options:
own: Own does not fit grammatically or contextually, as it implies possession rather than interference with signals.
march: March implies a steady movement, which does not relate to the concept of obscuring signals in this context.
highlight: Highlight means to emphasize or make something stand out, which is the opposite of what is intended in this context.
Correct answer: delicate
Explanation: The adjective 'delicate' accurately describes the instruments, indicating their fragility and sensitivity, which is essential in the context of scientific equipment.
Meaning: 'Delicate' means fragile or easily damaged, emphasizing the need for careful handling of the telescope's instruments.
Wrong options:
hard: Hard implies strength and durability, which contradicts the nature of the sensitive instruments being described.
rusty: Rusty suggests deterioration and is not applicable to the context of high-tech instruments.
unused: Unused implies that the instruments are not in operation, which does not fit the context of their intended function.
Correct answer: intriguing
Explanation: The adjective 'intriguing' effectively captures the interest and complexity of the gravitational properties, fitting well within the context of scientific exploration and discovery.
Meaning: 'Intriguing' means fascinating or interesting, highlighting the captivating nature of the gravitational properties being discussed.
Wrong options:
prolonging: Prolonging means to extend in time, which does not relate to the properties being described.
interpreting: Interpreting refers to explaining or understanding, which does not fit the context of describing the properties themselves.
torture: Torture implies severe suffering, which is not relevant or appropriate in the context of discussing gravitational properties.
