TEXT 1: How brightly the moon glows is a mystery, but maybe not for long.
“The lunar dark side may be the moon’s more mysterious face, but there’s something pretty basic scientists still don’t know about the bright side — namely, just how bright it is.
Current estimates of the moon’s brightness at any given time and vantage point are saddled with at least 5 percent uncertainty. That’s because those estimates are based on measurements from ground-based telescopes that gaze at the moon through the haze of Earth’s atmosphere.
Now, scientists have sent a telescope beyond the clouds on a high-altitude airplane in hopes of gauging the moon’s glow within about 1 percent or less uncertainty, the National Institute of Standards and Technology reports in a Nov. 19 news release.
Knowing the exact brightness of Earth’s celestial night-light could increase the reliability of data from Earth-observing satellites that use the moon’s steady glow to check that their sensors are working properly. Those satellites keep tabs on things like weather, crop health and dangerous algal blooms.”

Read the following article and answer question based on the text.
Faced with the unprecedented stream of migrants fleeing war and trauma in the Middle East and North Africa, Europe needs to take clear-sighted action.
For its part, the UK has agreed to take 20,000 refugees, a significant portion of whom will likely be children and orphans according to report. One key aspect in ensuring their smooth settlement in the UK will be providing these refugees with language training.
Many Syrians are well-educated and many speak fluent English. Others, however, do not speak English well enough to function professionally within the UK. The issue of language is so fundamental to our lives that we often overlook it. Several multi-million pound training contracts have failed to be delivered on account of not addressing the language barrier. All the goodwill, financial backing, and technical expertise to deliver needed medical, economic, military,engineering, or navigational training may be present; but unless there is a shared language in which to impart that knowledge, little will be accomplished.
One of the biggest misconceptions about language is that if you “just go to the country,” you’ll pick it up. Many people believe that immersion will guarantee fluency; yet you may well know several immigrants who have been in this country for years and still only speak broken English. You might also know dozens of expats in various countries across the world who have failed to pick up the local languages of their host countries. Training and effort are both necessary.
Though not a guarantee of fluency, immersion is a wonderful opportunity. The first issue we need to address with respect to refugees is ensuring that those who come will actually be immersed. That is, that they will be welcomed as part of larger communities, and not simply join communities of other refugees. On the other hand, immersion is just an opportunity, and in order to take full advantage of it, training and education are required. In terms of refugees, we need to consider options for the provision of language training, whether by self-study, classroom instruction, private tuition, or some combination of the three.
The array of needs is staggering. In truth, every language learner has a different set of learning objectives, and will require different training to meet those objectives. Coordinating the actual needs with providers in different regions and accounting for different personal schedules and start dates is a significant challenge. It is, however, a challenge that must be addressed immediately, as proficiency in English will be a key enabler of success for refugees in this country.
