In english, the general formula is verb + ed.
ex. visit -> visited
Since no one has created a machine capable of traveling through time that we know of, I can only draw inferences of what a time machine of this nature would function like from my imagination, and my knowledge of sci-fi films and novels. I imagine that the machine would hover above the surface of the ground, and shutter excessively for a little while, and then, somehow, channeling more energy than you could possibly fathom, it would disappear instantaneously with a blinding flash of light. It glides effortlessly though the distorted dimension of time, hurtling you through a series of intricate passageways that projected images depicting the universe throughout the course of time. It pulses a strange, multicolored energy from its exhaust pipe that evaporates into the “atmosphere” as the bulky piece of machinery continues to catapult you through the vortex of time. The control panel is equipped with an advanced artificial intelligence program, that voices the warning, “50 years until you’ve reached your desired time period” and you gaze the phantasmagorical world of time as it desintegrates before your eyes. Finally, you’ve arrived.
Answer:
B
Explanation:
First you can eliminate D because is shows nothing about whether the trip was fun.
While C shows they enjoyed the time, it could be 'what they needed' because it was relaxing or just an escape from reality. Not because it was incredibly fun.
A and B both show he most likely enjoyed the trip, but B is better because A still leaves room for questions. While in B you know that they enjoyed the trip because its directly said it was "the best trip ever", A he could be smiling because he's happy to see his dad or something else. B gives the most direct answer to the question.
