In this task, you're given a question, along with a context passage. The passage will not have a direct answer to the question, but can include some information and a clue for the answer. Assuming you can only obtain information about one entity in the passage, your job is to determine whether information from the passage can be used to answer the question. Indicate your choice as `a` for Yes or `b` for No.

Input: Consider Input: Question: How many Senators voted for the law that assigned Thebacon and all of its salts the control number 9737? Passage:Thebacon (INN; pronounced ), or dihydrocodeinone enol acetate, is a semisynthetic opioid that is similar to hydrocodone and is most commonly synthesised from thebaine. Thebacon is a derivative of acetyldihydrocodeine, where only the 6–7 double bond is saturated. Thebacon is marketed as its hydrochloride salt under the trade name Acedicon, and as its bitartrate under Diacodin and other trade names. The hydrochloride salt has a free base conversion ratio of 0.846. Other salts used in research and other settings include thebacon's phosphate, hydrobromide, citrate, hydroiodide, and sulfate. The US DEA Administrative Controlled Substance Control Number assigned by the Controlled Substances Act 1970 for thebacon and all of its salts is 9737.

Input: Consider Input: Question: What year was the treaty that opened up the Korean Peninsula to Japanese trade signed? Passage:Un'yō  was one of the ships dispatched to Kyūshū in 1874 during the Saga Rebellion. In May 1875, she carried diplomats to Busan in Korea in an attempt by the Japanese government to open diplomatic relations with the Joseon dynasty government. After they were rebuffed in these negotiations, the Japanese government again dispatched Un'yō in September 1875 under the command of Inoue Yoshika to provoke a military response, in what was later termed the Ganghwa Island incident. This eventually led to the Treaty of Ganghwa, which opened the Korean Peninsula to Japanese trade. In 1876, Un'yō  was assigned to assist in the suppression of the Hagi Rebellion, another uprising of disaffected former samurai. Un'yō  was severely damaged when she ran aground off the coast of the Kii Peninsula, and was scrapped the following year.

Input: Consider Input: Question: Which driver who won the New Zealand Grand Prix in the Lola T332 car had the fastest lap time? Passage:The T332 dominated the last three years of the US F5000 championship, with Briton Brian Redman taking the title three times in a row in 1974–76, his most serious rivals Al Unser and Mario Andretti, in 1974–75 in Parnelli T332C. Australian driver Warwick Brown used a T332 to win the 1975 Tasman Series as well as the 1975 New Zealand Grand Prix. In doing so he became the only Australian driver to ever win the Tasman Series. New Zealand driver Ken Smith also used a Lola T332 to win the 1976 New Zealand Grand Prix. Ken Smith had obtained Redman's 1974 US winning chassis and a couple of extremely powerful US F5000 chev engines. Lawrence, after a serious accident in the 72 NZGP regained competitive form in a new T332 in the 1974 Tasman and by 1975 had upgraded his chassis to the specs of Andretti's US car and running with real sponsorship from Malboro, Singapore Airlines and Wix, was Warwick Brown's most serious rival during the 1975 Tasman. As a side note, both the 1975 and 1976 New Zealand Grands Prix were held at Pukekohe Park Raceway. It was generally thought in the 1975 Tasman the two best drivers, Graham MacRae in a MacRae GM2 and Chris Amon in a Talon (a modified version of the GM2) were very much at a disadvantage compared with Lawrence, Brown and Smith in the Lola 332T, although to some extent that was compensated by the very fast Firestone F5000 tyres used by McRae for the last time in NZ which meant MacRae took pole or deadheated for pole time in the four kiwi rounds of the last Tasman. MacRae himself found his own T332 far faster than his GM2 in the 1974/75 US Travellers Cheque F5000 series. Although not able to equal the engine preparation of the Haas or Parnelli teams running at F1 level, even in 1975 at Watkins Geln, Lagua Seca and Long Beach, McRae in a T332 was still as quick as Jarier or Unser while his T332 lasted. In Australasia the T400 never matched the T332 although after its disastrous 1975 series, Max Stewarts T400 was often competitive in 1976 and 1977. In the Shellsport F5000 series in 1975, Peter Gethin and Pilete's T400 was probably quicker than the best T332s of Guy Edwards and Ian Ashley and in 1976 Keith Holland in a T400 often matched Edward's and David Purley 3.6 March and Chevron cars. The last two new T332c F5000s in 1977 were built for Alan Jones for the 1977 Australian Tasman rounds and Keith Holland Shellsport campaign that year.
