The world-famous art museum Musée d’Orsay    1     (house) some of the best-known Impressionist     2     (paint) of the 19th century. When I     3     (wander) there and laid eyes on the masterpieces, mostly I    4     (strike) by the works of the two Impressionists Claude Monet and Pierre·Auguste Renoir.

The law also includes a limit for dog owners on     5     number of dogs they can keep.
