This task is about creating an unanswerable question based on a given passage. Construct a question that looks relevant to the given context but is unanswerable. Following are a few suggestions about how to create unanswerable questions:
(i) create questions which require satisfying a constraint that is not mentioned in the passage
(ii) create questions which require information beyond what is provided in the passage in order to answer
(iii) replace an existing entity, number, date mentioned in the passage with other entity, number, date and use it in the question
(iv) create a question which is answerable from the passage and then replace one or two words by their antonyms or insert/remove negation words to make it unanswerable.

Q: Passage: To make pulp from wood, a chemical pulping process separates lignin from cellulose fibres. This is accomplished by dissolving lignin in a cooking liquor, so that it may be washed from the cellulose; this preserves the length of the cellulose fibres. Paper made from chemical pulps are also known as wood-free papersnot to be confused with tree-free paper; this is because they do not contain lignin, which deteriorates over time. The pulp can also be bleached to produce white paper, but this consumes 5% of the fibres; chemical pulping processes are not used to make paper made from cotton, which is already 90% cellulose.

A: What is separated from pulp to make wood?

Q: Passage: Turner Classic Movies essentially operates as a commercial-free service, with the only advertisements on the network being shown between features which advertise TCM products, network promotions for upcoming special programs and the original trailers for films that are scheduled to be broadcast on TCM (particularly those that will air during the primetime hours), and featurettes about classic film actors and actresses. In addition to this, extended breaks between features are filled with theatrically released movie trailers and classic short subjects from series such as The Passing Parade, Crime Does Not Pay, Pete Smith Specialties, and Robert Benchley under the banner name TCM Extras (formerly One Reel Wonders). In 2007, some of the short films featured on TCM were made available for streaming on TCM's website. Partly to allow these interstitials, Turner Classic Movies schedules its feature films either at the top of the hour or at :15, :30 or :45 minutes past the hour, instead of in timeslots of varying five-minute increments.

A: What were TCM products previously known as?
