In this task, you will be given a passage to read. A fill in the blank question will be given to you.  Your answer should fit the blank appropriately.

 Townsend draws influence from a wide range of music genres , most prominently heavy metal . Townsend has cited , among others , Judas Priest , W.A.S.P. , Frank Zappa , Broadway musicals , ABBA , new @-@ age music , Zoviet France , King 's X , Morbid Angel , Barkmarket , Grotus , Jane 's Addiction , Metallica , Cop Shoot Cop and Fear Factory as his influences , and has also expressed his admiration for Meshuggah on several occasions , calling them  the best metal band on the planet  . Townsend lists Paul Horn and Ravi Shankar as the  two most important musicians in his life. The two songs that Townsend credits with changing the way he thought about music are The Burning Down by King 's X , and  Up the Beach  by Jane 's Addiction . City was influenced by bands such as Foetus and Cop Shoot Cop , and The New Black 's influences were Meshuggah , and  more traditional metal like Metallica . He is also influenced by orchestral and classical composers such as John Williams , Trevor Jones and Igor Stravinsky .  fill in the blank  : Townsend __________________ influence from a wide range of music genres , most prominently heavy metal .

 Catalytic reagents have been less successful , with most variations suffering from poor yield , poor enantioselectivity , or both . There are also issues with substrate scope , most having limitations with methylene transfer and aliphatic aldehydes . The trouble stems from the need for a nucleophilic sulfide that efficiently generates the ylide which can also act as a good leaving group to form the epoxide . Since the factors underlying these desiderata are at odds , tuning of the catalyst properties has proven difficult . Shown below are several of the most successful catalysts along with the yields and enantiomeric excess for their use in synthesis of ( E ) -stilbene oxide . Aggarwal has developed an alternative method employing the same sulfide as above and a novel alkylation involving a rhodium carbenoid formed in situ . The method too has limited substrate scope , failing for any electrophiles possessing basic substituents due to competitive consumption of the carbenoid . Treaty of Ciudad Juárez  The Treaty of Ciudad Juárez was a peace treaty signed between the then President of Mexico , Porfirio Díaz , and the revolutionary Francisco Madero on May 21 , 1911 . The treaty put an end to the fighting between forces supporting Madero and those of Díaz and thus concluded the initial phase of the Mexican Revolution . The treaty stipulated that Díaz , as well as his vice president Ramón Corral , were to step down by the end of May , and that he was to be replaced by Francisco León de la Barra as interim president and hold presidential elections . Those who had suffered losses due to the revolution would be the indemnified , and there would be a general amnesty . Díaz resigned on May 25 , and interim president Francisco León de la Barra was the new incumbent . Díaz and his family , his vice president Corral , plus José Yves Limantour and Rosendo Pineda left Mexico for exile . Significantly , the treaty did not mention or institute any social reforms that Madero had vaguely promised on previous occasions . It also left the Porfirian state essentially intact . Additionally , Madero supported the unpopular idea that all land disputes were to be settled through the courts , staffed by the old judges , a decision that led to outbreaks of sporadic violence , particularly in rural areas . On June 7 , 1911 , Madero entered Mexico City . In October 1911 he was elected president , under the banner of the Partido Constitucional Progresista , along with José María Pino Suárez , his new running mate as vice @-@ president . Madero pushed aside Francisco Vázquez Gómez , the vice presidential candidate for the Anti @-@ Reelectionist Party in 1910 , as being too moderate . fill in the blank  :  Catalytic reagents have been less successful , with most variations suffering from poor __________________ , poor enantioselectivity , or both .

Private flying can be for both recreational purposes and personal transport , using aircraft that are owned individually , collectively as part of a syndicate , or rented from a flying club . A survey of pilots conducted between 2001 and 2002 indicated that the most common purposes of recreational flights were local flights near the base aerodrome , visits to other aerodromes , and day trips away . Half of all flights landed at the same aerodrome they departed from , and only 9 per cent involved an overnight stay away from home .Private flying is most associated with the traditional form of factory @-@ produced two and four @-@ seater , single piston @-@ engine training and touring aircraft . Examples of these are the Cessna 152 , Cessna 172 , and Piper PA28 Cherokee , all with their origins in the 1950s , and the more modern designs of Cirrus . The average cost per hour to fly such aircraft has been estimated to be £ 133 , compared to an estimated £ 77 per hour for gliders , and a reported £ 35 per hour for microlights . Recent trends have seen an increase in the use of microlights , and also in recreational helicopter flying following the introduction of smaller and cheaper machines such as the Robinson R22 and R44 . Another growth area in private flying in recent years has been in the use of amateur built aircraft , such as the Van 's Aircraft RV @-@ 4 and the Europa .There is a strong vintage aircraft movement in the UK , with two @-@ thirds of the 500 registered historic aircraft active . These cover the whole spectrum of civil and military aviation , examples being the de Havilland Dragon Rapide airliner of the 1930s , and the World War II ( WWII ) Spitfire fighter . There are many post @-@ WWII aircraft which could also be considered historic under a looser definition , including for example 60 ex @-@ military jets such as the Hawker Hunter . Historic aircraft are regular exhibits at air displays , which are claimed to be the second most popular spectator activity after football in the UK.fill in the blank  : Private flying can be for both recreational __________________ and personal transport , using aircraft that are owned individually , collectively as part of a syndicate , or rented from a flying club .
