Input: Article: The usefulness of the canals was short-lived, though some have now been restored for recreation. The 19th century also saw the construction of railways to and through Somerset. The county was served by five pre-1923 Grouping railway companies: the Great Western Railway (GWR); a branch of the Midland Railway (MR) to Bath Green Park (and another one to Bristol); the Somerset and Dorset Joint Railway, and the London and South Western Railway (L&SWR). The former main lines of the GWR are still in use today, although many of its branch lines were scrapped under the notorious Beeching Axe. The former lines of the Somerset and Dorset Joint Railway closed completely, as has the branch of the Midland Railway to Bath Green Park (and to Bristol St Philips); however, the L&SWR survived as a part of the present West of England Main Line. None of these lines, in Somerset, are electrified. Two branch lines, the West and East Somerset Railways, were rescued and transferred back to private ownership as "heritage" lines. The fifth railway was a short-lived light railway, the Weston, Clevedon and Portishead Light Railway. The West Somerset Mineral Railway carried the iron ore from the Brendon Hills to Watchet.

Now answer this question: How many railways served the county 

Output: The county was served by five pre-1923 Grouping railway companies

Input: Article: In general, German bombers were likely to get through to their targets without too much difficulty. It was to be some months before an effective night fighter force would be ready, and anti-aircraft defences only became adequate after the Blitz was over, so ruses were created to lure German bombers away from their targets. Throughout 1940, dummy airfields were prepared, good enough to stand up to skilled observation. A number[clarification needed] of bombs fell on these diversionary ("Starfish") targets.

Now answer this question: What kind of airfields were prepared to stand up to skilled observers? 

Output: dummy

Input: Article: In 2010, there were concerns among Tajik officials that Islamic militarism in the east of the country was on the rise following the escape of 25 militants from a Tajik prison in August, an ambush that killed 28 Tajik soldiers in the Rasht Valley in September, and another ambush in the valley in October that killed 30 soldiers, followed by fighting outside Gharm that left 3 militants dead.

Now answer this question: Why was there concerns in 2010?

Output:
that Islamic militarism in the east of the country was on the rise following the escape of 25 militants from a Tajik prison in August
