This task involves creating questions from a given passage that involve some kind of complex reasoning (including numerical reasoning).
The generated questions must require looking at more than one part of the passage to answer. Try to use a variety of reasoning types in your questions (some of the sample reasoning types are illustrated in the 'positive examples' field) and also have a variety of answer types (spans, numbers, dates). A span is a continuous phrase taken directly from the passage or question. In such questions, the answer spans are recommended to be five words. Questions with answer type "number", are expected to start with "How many". For instance, "How long did an event last?" can be phrased as "How many years did an event last?". To increase diversity, try to create more questions for which the answer will be multiple spans. Please create questions that require AT LEAST 2 arithmetic operations as illustrated in the 'positive examples' field. You are encouraged to try DIFFERENT COMBINATIONS of operations and not just limit to the combinations shown in those examples. The more challenging questions you create, the better it is.
Q: Passage: Statistics on freight are specified in terms of the weight of freight lifted, and the net tonne kilometre, being freight weight multiplied by distance carried. 116.6 million tonnes of freight was lifted in the 20134 period, against 138 million tonnes in 19867, a decrease of 16%. However, a record 22.7 billion net tonne kilometres (14 billion net ton miles) of freight movement were recorded in 2013-4, against 16.6 billion (10.1 billion) in 19867, an increase of 38%. Coal makes up 36% of the total net tonne kilometre, though its share is declining. Rail freight has increased its market share since privatisation (by net tonne kilometres) from 7.4% in 1998 to 11.1% in 2013. Recent growth is partly due to more international services including the Channel Tunnel and Port of Felixstowe, which is containerised. Nevertheless, network bottlenecks and insufficient investment in catering for 9 6" high shipping containers restrict growth.
A:
How many fewer millions of tonnes of freight was lifted in 2013-14 than in 1986-87?
