PROBLEM: Passage: A sequel to Spectre will begin development in spring 2016. Sam Mendes has stated he will not return to direct the next 007 film. Christoph Waltz has signed on for two more films in the series, but his return depends on whether or not Craig will again portray Bond.

PROBLEM: Passage: Extension causes the rock units as a whole to become longer and thinner. This is primarily accomplished through normal faulting and through the ductile stretching and thinning. Normal faults drop rock units that are higher below those that are lower. This typically results in younger units being placed below older units. Stretching of units can result in their thinning; in fact, there is a location within the Maria Fold and Thrust Belt in which the entire sedimentary sequence of the Grand Canyon can be seen over a length of less than a meter. Rocks at the depth to be ductilely stretched are often also metamorphosed. These stretched rocks can also pinch into lenses, known as boudins, after the French word for "sausage", because of their visual similarity.

SOLUTION: What is another word for thinning rocks in French?

PROBLEM: Passage: Illustrated humour periodicals were popular in 19th-century Britain, the earliest of which was the short-lived The Glasgow Looking Glass in 1825. The most popular was Punch, which popularized the term cartoon for its humorous caricatures. On occasion the cartoons in these magazines appeared in sequences; the character Ally Sloper featured in the earliest serialized comic strip when the character began to feature in its own weekly magazine in 1884.

SOLUTION:
What was the last illustrated humor periodical in Britain during the 19th century?
