Context and question: Southampton Water has the benefit of a double high tide, with two high tide peaks, making the movement of large ships easier. This is not caused as popularly supposed by the presence of the Isle of Wight, but is a function of the shape and depth of the English Channel. In this area the general water flow is distorted by more local conditions reaching across to France.
In addition to its shape, what property of the English Channel affects water flow in Southampton Water?
Answer: depth
Context and question: Finally, an introduced species may unintentionally injure a species that depends on the species it replaces. In Belgium, Prunus spinosa from Eastern Europe leafs much sooner than its West European counterparts, disrupting the feeding habits of the Thecla betulae butterfly (which feeds on the leaves). Introducing new species often leaves endemic and other local species unable to compete with the exotic species and unable to survive. The exotic organisms may be predators, parasites, or may simply outcompete indigenous species for nutrients, water and light.
What does introducing new spinosas often do?

Context and question: When the Xbox 360 was released, Microsoft's online gaming service Xbox Live was shut down for 24 hours and underwent a major upgrade, adding a basic non-subscription service called Xbox Live Silver (later renamed Xbox Live Free) to its already established premium subscription-based service (which was renamed Gold). Xbox Live Free is included with all SKUs of the console. It allows users to create a user profile, join on message boards, and access Microsoft's Xbox Live Arcade and Marketplace and talk to other members. A Live Free account does not generally support multiplayer gaming; however, some games that have rather limited online functions already, (such as Viva Pinata) or games that feature their own subscription service (e.g. EA Sports games) can be played with a Free account. Xbox Live also supports voice the latter a feature possible with the Xbox Live Vision.
How long was voice support down after its launch?
