Detailed Instructions: In this task, you will be presented with a passage and have to answer a question based on your understanding of the events inferred from the passage. Try to find the best answer that is most likely to fill in "_". Note that the URLs in the text have been replaced with [Link].
See one example below:
Problem: For four years we have waited expectantly for the pitter patter of tiny paws. Soon, that wait could finally be over. Tian Tian, the UK's only female giant panda, has conceived and could give birth to a cub as early as August. However Edinburgh Zoo, where the pandas live, have warned people 'not to get too excited' as the process is 'extremely complex'. Moreover, on the two previous occasions keepers inseminated Tian Tian - whose name means 'Sweetie' - she has failed to produce a panda cub. She was artificially inseminated again in March this year, but keepers at the zoo say implantation - when a fertilised egg attaches to the uterus - has not yet occurred.Tian Tian has conceived and could give birth to a cub as early as AugustShe has been inseminated twice before but so far failed to produce a cubTian Tian and Yang Guang arrived in 2011 from China to great fanfareOn loan at £600k a year, became first giant pandas to live in UK for 17 years 
 Questions:Under the terms of the agreement any cubs will return to _ at the age of two, the age at which they would normally leave their mother in the wild.
Solution: China
Explanation: This is a good example. Based on the passage, any cubs will return to China at the age of two

Problem: Stunning footage has emerged showing wave-like clouds over the skies of Colorado. The Breckenridge Resort tweeted the video to highlight something known as Kelvin-Helmholtz waves, which can be found all over the solar system, including in Saturn's atmosphere. This beautiful pattern emerges in clouds when two different layers of air in the atmosphere are moving at different speeds. Kelvin-Helmholtz waves are everywhere. From Earth's clouds and ocean surfaces to the atmosphere of Jupiter, these waves have a striking pattern - a series of curled hills moving steadily in one direction. The shape of this pattern has a simple cause. A fast fluid, say wind, moving past a slower one, such as water, naturally creates this wave shape.Pattern created when when two layers of air move at different speedsThese Kelvin-Helmholtz waves are more common than first thoughtCan also be found in Saturn's atmopshere and Earth's magnetosphere 
 Question:The first paper compared Kelvin-_ waves to what was seen in the solar wind, the second team compared it to what was happening closer to Earth.
Solution:
Helmholtz
