Question

space travel
for years, science fiction filmmakers and novelists have been creating alternative, habitable planets in parallel universes. many of their fans ask: do these planets really exist? if they do, can humans reach these planets?
the reality of planets beyond our solar system is not a piece of fiction. outer space is filled with millions of galaxies and, in each galaxy, there are thousands of stars and planets. whether or not humans can reach these distant planets is debatable. in order to understand why this has created a debate, one should understand the design of our universes many galaxies.
to begin with, the universe is immeasurably vast and expanding. in order to cover vast distances, one needs speed. on the other hand, the distance in space is measured by light years. the fastest traveling entity known to humans is light. it travels at the speed of 186,000 miles per second! the distance traveled by light in a year is called one light year. in other words, in order to travel a distance of one light year, one should travel at 186,000 miles per second - if thats ever possible - for a year! for this reason, visiting a neighboring

read this sentence.
at present, humans cannot reach distant planets on account of the universes vast size.
based on the passage, which statement is connected to this point?
○a. only by exploring can one unravel the mysteries of outer space.
○b. outer space has been a favorite subject of novelists and filmmakers.
○c. nicolaus copernicus was the first person to claim that they earth revolved around the sun.
○d. wormholes and teleportation might make it possible to travel through space in the future.

Explanation:

The original sentence is about the reason (universe's vast size) why humans can't reach distant planets. Option D talks about future possibilities (wormholes and teleportation) related to space travel, which is connected as it addresses the issue of overcoming the vastness (the problem in the original sentence). Option A is about exploring mysteries, not directly related to the vast - size - hindrance. Option B is about outer space being a subject for novelists/filmmakers, not relevant. Option C is about Copernicus' theory, not related.

Answer:

D. Wormholes and teleportation might make it possible to travel through space in the future.
