Team Composition
In a large organization, it is often the case that different roles emerge. In Tayloristic teams, these different roles are grouped together as a number of role-based teams each of which contains members of the same role. In contrast, agile teams use cross-functional teams. Such a team draws together individuals performing all defined roles. Rotations from one role to another are common. It is also possible to have highly specialized experts (for example, security analysts and usability engineers) shared among several teams in an organization.
One advantage to role-based teams is that teams whose work products are independent of each other can work in parallel as long as there is not much knowledge flow among the different functional sub-team. However, in knowledgeintensive software development that demands information flow from different functional sub teams, role-based teams tend to lead to islands of knowledge and difficulty in its sharing among all the teams. As hand-offs between teams usually are based on document flow, the knowledge of one team that is required by the other team must be externalized and documented. Although reviews try to minimize the knowledge loss, externalization and documentation processes cannot guarantee that all knowledge is captured and even if most of it was rigorously captured, there is still no guarantee or way to check its correctness till the project sign-off.
Cross-functional teams should be used to facilitate better knowledge transfer. This is especially the case for agile methods since they are recommended to be used where there is a lot of uncertainty and unknown knowledge about the domain and system requirements, and the technologies to be used are new and unexplored.

The following are aspects or concerns of a Genre Approach to English as a second language:
I. The relationship between texts and their contexts.
II. The purpose or intention of a text.
III. Reader has the main role.
IV. Writing as a social activity.
V. Teacher’s role is authoritarian.
Choose the CORRECT option:
I have suggested that many, if not most teachers, could usefully adjust the values they emphasise. Here, three of them:
1. From Short-Term to Long-Term Aims
Learning a foreign language can be a valuable, long-term personal asset for the student. lt can be inhibited by over-emphasising short-term objectives — tests, pressure to speak before you are ready etc.
2. From Knowledge to Skill
Knowledge involves answers and explanations and is necessary, but not sufficient. What matters is not what you know, but what you can do. ‘Knowing’ a foreign language may be interesting; the ability to use it is life-enhancing.
3. From Accuracy to Communication
Successful communication always involves at least limited accuracy. Accuracy need not involve communication at all. Communication is a wider, more useful concept; successful language is more valuable than language which is only accurate.

Text: “How to spot fake news”
Every time you're online, you are bombarded by pictures, articles, links and videos trying to tell their story. Unfortunately, not all of these stories are true. Sometimes they want you to click on another story or advertisement at their own site, other times they want to upset people for political reasons. These days it's so easy to share information. These stories circulate quickly, and the result is … fake news.
There is a range of fake news: from crazy stories which people easily recognize to more subtle types of misinformation. Experts in media studies and online psychology have been examining the fake news phenomenon. Read these tips, and don't get fooled!
1. Check the source
Look at the website where the story comes from. Does it look real? Is the text well written? Are there a variety of other stories or is it just one story? Fake news websites often use addresses that sound like real newspapers, but don't have many real stories about other topics. If you aren't sure, click on the 'About' page and look for a clear description of the organization.
2. Watch out for fake photos
Many fake news stories use images that are Photoshopped or taken from an unrelated site. Sometimes, if you just look closely at an image, you can see if it has been changed. Or use a tool like Google Reverse Image search. It will show you if the same image has been used in other contexts.
3. Check the story is in other places
Look to see if the story you are reading is on other news sites that you know and trust. If you do find it on many other sites, then it probably isn't fake (although there are some exceptions), as many big news organizations try to check their sources before they publish a story.
4. Look for other signs
There are other techniques that fake news uses. These include using ALL CAPS and lots of ads that pop up when you click on a link. Also, think about how the story makes you feel. If the news story makes you angry, it's probably designed to make you angry.
If you know these things about online news, and can apply them in your everyday life, then you have the control over what to read, what to believe and most importantly what to share. If you find a news story that you know is fake, the most important advice is: don't share it!

“Tomato crisis” spreads panic in Nigeria
Making jollof rice, a beloved traditional dish in Nigeria, has suddenly become very expensive. Tomatoes, one of its main ingredients and a staple of Nigerian cuisine, are going for $2 each ____ local markets, with wholesale baskets costing as much as N42,000, or $212, Kaduna state agriculture commissioner Manzo Daniel told AFP.
The culprit is a moth called Tuta absoluta, which has destroyed crops in the northern Kaduna state, forcing the local government to declare a state of emergency. “It is a serious problem. The disease has affected production and consumption, prices are continuing to rise and there is no availability,” Shehu Sani, Senator for Kaduna Central, told CNN.
The area, which contributes strongly to Nigeria’s overall production, has already seen losses of millions of dollars, according to Sani. “Many depend ____ tomato farming for their livelihood and tomatoes are an indispensable part of the diet. People cannot do without them,” he said.
The tomato crisis comes on the heels of a recent fuel shortage and a general rise in commodity prices due to inflation and a lack of foreign currency. In local towns, the problem has been labeled “Tomato Ebola”. “People are panicking, because attaching that name to a staple food has worsened the situation,” said Sani. Even those who can afford to buy find it difficult to trust any tomato product, and some have started buying imported tinned tomatoes. “Nobody knows now which tomatoes are safe to eat and some people are avoiding them altogether.”
Nigerians have taken to Twitter to lament the situation, pointing out ____ playful disbelief that while they have to pay dearly for tomatoes, at an annual festival in Spain they are wasted for fun. The next ‘La Tomatina’ festival isn’t due until August, but ____ then Nigerians hope they’ll have gone back to tomato-normality.
