Problem: Detroit:

The city of Detroit and other private-public partnerships have attempted to catalyze the region's growth by facilitating the building and historical rehabilitation of residential high-rises in the downtown, creating a zone that offers many business tax incentives, creating recreational spaces such as the Detroit RiverWalk, Campus Martius Park, Dequindre Cut Greenway, and Green Alleys in Midtown. The city itself has cleared sections of land while retaining a number of historically significant vacant buildings in order to spur redevelopment; though it has struggled with finances, the city issued bonds in 2008 to provide funding for ongoing work to demolish blighted properties. Two years earlier, downtown reported $1.3 billion in restorations and new developments which increased the number of construction jobs in the city. In the decade prior to 2006, downtown gained more than $15 billion in new investment from private and public sectors.

What part of Detroit is Green Alleys located in?
---
A: Midtown

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Solar power is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP). CSP systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. PV converts light into electric current using the photoelectric effect.
How is sunlight converted into electricity?
A: either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP)


Context and question: Memorization is a method of learning that allows an individual to recall information verbatim. Rote learning is the method most often used. Methods of memorizing things have been the subject of much discussion over the years with some writers, such as Cosmos Rossellius using visual alphabets. The spacing effect shows that an individual is more likely to remember a list of items when rehearsal is spaced over an extended period of time. In contrast to this is cramming: an intensive memorization in a short period of time. Also relevant is the Zeigarnik effect which states that people remember uncompleted or interrupted tasks better than completed ones. The so-called Method of loci uses spatial memory to memorize non-spatial information.
What is the least widely used way in learning?
Answer: unanswerable


Question: On October 3, 2010, Public Safety Canada unveiled Canada’s Cyber Security Strategy, following a Speech from the Throne commitment to boost the security of Canadian cyberspace. The aim of the strategy is to strengthen Canada’s "cyber systems and critical infrastructure sectors, support economic growth and protect Canadians as they connect to each other and to the world." Three main pillars define the strategy: securing government systems, partnering to secure vital cyber systems outside the federal government, and helping Canadians to be secure online. The strategy involves multiple departments and agencies across the Government of Canada. The Cyber Incident Management Framework for Canada outlines these responsibilities, and provides a plan for coordinated response between government and other partners in the event of a cyber incident. The Action Plan 2010–2015 for Canada's Cyber Security Strategy outlines the ongoing implementation of the strategy.
Is there an answer to this question: Why was a cyber security plan unveiled in October of 2010?
