Here is a question about this article: In June 1986, Madonna released her third studio album, True Blue, which was inspired by and dedicated to Sean Penn. Rolling Stone magazine was generally impressed with the effort, writing that the album "sound[s] as if it comes from the heart". It resulted in three singles making it to number-one on the Billboard Hot 100: "Live to Tell", "Papa Don't Preach" and "Open Your Heart", and two more top-five singles: "True Blue" and "La Isla Bonita". The album topped the charts in over 28 countries worldwide, an unprecedented achievement at the time, and became her best-selling studio album of her career to this date with sales of 25 million. In the same year, Madonna starred in the critically panned film Shanghai Surprise, for which she was awarded the Golden Raspberry Award for "worst actress". She made her theatrical debut in a production of David Rabe's Goose and Tom-Tom; the film and play both co-starred Penn. The next year, Madonna was featured in the film Who's That Girl. She contributed four songs to its soundtrack, including the title track and "Causing a Commotion".
What is the answer to this question: Madonna's album topped in how many countries chart worldwide?
****
So... 28 countries

Here is a question about this article: Another potential weapon system for anti-aircraft use is the laser. Although air planners have imagined lasers in combat since the late 1960s, only the most modern laser systems are currently reaching what could be considered "experimental usefulness". In particular the Tactical High Energy Laser can be used in the anti-aircraft and anti-missile role. If current developments continue, some[who?] believe it is reasonable to suggest that lasers will play a major role in air defence starting in the next ten years.
What is the answer to this question: What laser can currently be used in the type of role that was first thought of in the late 1960s?

So... Tactical High Energy Laser

Here is a question about this article: In the early 5th century, the deep crisis suffered by the Roman Empire allowed different tribes of Central Europe (Suebi, Vandals and Alani) to cross the Rhine and penetrate into the rule on 31 December 406. Its progress towards the Iberian Peninsula forced the Roman authorities to establish a treaty (foedus) by which the Suebi would settle peacefully and govern Galicia as imperial allies. So, from 409 Galicia was taken by the Suebi, forming the first medieval kingdom to be created in Europe, in 411, even before the fall of the Roman Empire, being also the first Germanic kingdom to mint coinage in Roman lands. During this period a Briton colony and bishopric (see Mailoc) was established in Northern Galicia (Britonia), probably as foederati and allies of the Suebi. In 585, the Visigothic King Leovigild invaded the Suebic kingdom of Galicia and defeated it, bringing it under Visigoth control.
What is the answer to this question: At the end of which year did Central Europe tribes invade the Roman Empire?

So...
406
