Ethanol is a versatile solvent, miscible with water and with many organic solvents, including acetic acid, acetone, benzene, carbon tetrachloride, chloroform, diethyl ether, ethylene glycol, glycerol, nitromethane, pyridine, and toluene. It is also miscible with light aliphatic hydrocarbons, such as pentane and hexane, and with aliphatic chlorides such as trichloroethane and tetrachloroethylene.Ethanol's miscibility with water contrasts with the immiscibility of longer-chain alcohols (five or more carbon atoms), whose water miscibility decreases sharply as the number of carbons increases. The miscibility of ethanol with alkanes is limited to alkanes up to undecane: mixtures with dodecane and higher alkanes show a miscibility gap below a certain temperature (about 13 °C for dodecane). The miscibility gap tends to get wider with higher alkanes and the temperature for complete miscibility increases.

Question: What is ethanol?
Answer: a versatile solvent, miscible with water and with many organic solvents
Cardiovascular disease (CVD) is a class of diseases that involve the heart or blood vessels. CVD includes coronary artery diseases (CAD) such as angina and myocardial infarction (commonly known as a heart attack). Other CVDs include stroke, heart failure, hypertensive heart disease, rheumatic heart disease, cardiomyopathy, heart arrhythmia, congenital heart disease, valvular heart disease, carditis, aortic aneurysms, peripheral artery disease, thromboembolic disease, and venous thrombosis.The underlying mechanisms vary depending on the disease. Coronary artery disease, stroke, and peripheral artery disease involve atherosclerosis. This may be caused by high blood pressure, smoking, diabetes mellitus, lack of exercise, obesity, high blood cholesterol, poor diet, and excessive alcohol consumption, among others. High blood pressure is estimated to account for approximately 13% of CVD deaths, while tobacco accounts for 9%, diabetes 6%, lack of exercise 6% and obesity 5%. Rheumatic heart disease may follow untreated strep throat.It is estimated that up to 90% of CVD may be preventable. Prevention of CVD involves improving risk factors through: healthy eating, exercise, avoidance of tobacco smoke and limiting alcohol intake. Treating risk factors, such as high blood pressure, blood lipids and diabetes is also beneficial. Treating people who have strep throat with antibiotics can decrease the risk of rheumatic heart disease. The use of aspirin in people, who are otherwise healthy, is of unclear benefit.Cardiovascular diseases are the leading cause of death globally. This is true in all areas of the world except Africa. Together CVD resulted in 17.9 million deaths (32.1%) in 2015, up from 12.3 million (25.8%) in 1990. Deaths, at a given age, from CVD are more common and have been increasing in much of the developing world, while rates have declined in most of the developed world since the 1970s. Coronary artery disease and stroke account for 80% of CVD deaths in males and 75% of CVD deaths in females. Most cardiovascular disease affects older adults. In the United States 11% of people between 20 and 40 have CVD, while 37% between 40 and 60, 71% of people between 60 and 80, and 85% of people over 80 have CVD. The average age of death from coronary artery disease in the developed world is around 80 while it is around 68 in the developing world. Diagnosis of disease typically occurs seven to ten years earlier in men as compared to women.

Question: What kind of smoke should you avoid to prevent CVD?
Answer: tobacco

Amino acids vary in their ability to form the various secondary structure elements. Proline and glycine are sometimes known as "helix breakers" because they disrupt the regularity of the α helical backbone conformation; however, both have unusual conformational abilities and are commonly found in turns. Amino acids that prefer to adopt helical conformations in proteins include methionine, alanine, leucine, glutamate and lysine ("MALEK" in amino-acid 1-letter codes); by contrast, the large aromatic residues (tryptophan, tyrosine and phenylalanine) and Cβ-branched amino acids (isoleucine, valine, and threonine) prefer to adopt β-strand conformations. However, these preferences are not strong enough to produce a reliable method of predicting secondary structure from sequence alone.

Question: What type of DNA structure cannot be predicted reliably using this method?
Answer: secondary structure
Although Let It Be was the Beatles' final album release, it was largely recorded before Abbey Road. The project's impetus came from an idea Martin attributes to McCartney, who suggested they "record an album of new material and rehearse it, then perform it before a live audience for the very first time – on record and on film". Originally intended for a one-hour television programme to be called Beatles at Work, in the event much of the album's content came from studio work beginning in January 1969, many hours of which were captured on film by director Michael Lindsay-Hogg. Martin has said that the project was "not at all a happy recording experience. It was a time when relations between the Beatles were at their lowest ebb." Lennon described the largely impromptu sessions as "hell ... the most miserable ... on Earth", and Harrison, "the low of all-time". Irritated by both McCartney and Lennon, Harrison walked out for five days. Upon returning, he threatened to leave the band unless they "abandon[ed] all talk of live performance" and instead focused on finishing a new album, initially titled Get Back, using songs recorded for the TV special. He also demanded they cease work at Twickenham Film Studios, where the sessions had begun, and relocate to the newly finished Apple Studio. The other band members agreed, and the idea came about to salvage the footage shot for the TV production for use in a feature film.

Question: Who was the idea's brainchild?
Answer: McCartney
Capitol Records' lack of interest throughout 1963 did not go unnoticed, and a competitor, United Artists Records, encouraged their film division to offer the Beatles a three-motion-picture deal, primarily for the commercial potential of the soundtracks in the US. Directed by Richard Lester, A Hard Day's Night involved the band for six weeks in March–April 1964 as they played themselves in a musical comedy. The film premiered in London and New York in July and August, respectively, and was an international success, with some critics drawing comparison with the Marx Brothers.United Artists released a full soundtrack album for the North American market, combining Beatles songs and Martin's orchestral score; elsewhere, the group's third studio LP, A Hard Day's Night, contained songs from the film on side one and other new recordings on side two. According to Erlewine, the album saw them "truly coming into their own as a band. All of the disparate influences on their first two albums coalesced into a bright, joyous, original sound, filled with ringing guitars and irresistible melodies." That "ringing guitar" sound was primarily the product of Harrison's 12-string electric Rickenbacker, a prototype given to him by the manufacturer, which made its debut on the record.

Question: How many albums were made before this one?
Answer: two albums
Freed from the burden of touring, the Beatles embraced an increasingly experimental approach as they recorded Sgt. Pepper's Lonely Hearts Club Band, beginning in late November 1966. According to engineer Geoff Emerick, the album's recording took over 700 hours. He recalled the band's insistence "that everything on Sgt. Pepper had to be different. We had microphones right down in the bells of brass instruments and headphones turned into microphones attached to violins. We used giant primitive oscillators to vary the speed of instruments and vocals and we had tapes chopped to pieces and stuck together upside down and the wrong way around." Parts of "A Day in the Life" featured a 40-piece orchestra. The sessions initially yielded the non-album double A-side single "Strawberry Fields Forever"/"Penny Lane" in February 1967; the Sgt. Pepper LP followed in June. The musical complexity of the records, created using relatively primitive four-track recording technology, astounded contemporary artists. Among music critics, acclaim for the album was virtually universal. Gould writes:

Question: What did Geoff Emerick recall about Sgt. Pepper's Lonely Hearts?
Answer: everything on Sgt. Pepper had to be different

Answer: Scott Schinder and Andy Schwartz
In an effort to alleviate tensions within the band and improve the quality of their live sound, Harrison invited keyboardist Billy Preston to participate in the last nine days of sessions. Preston received label billing on the "Get Back" single – the only musician ever to receive that acknowledgment on an official Beatles release. At the conclusion of the rehearsals, the band could not agree on a location to film a concert, rejecting several ideas, including a boat at sea, a lunatic asylum, the Tunisian desert, and the Colosseum. Ultimately, what would be their final live performance was filmed on the rooftop of the Apple Corps building at 3 Savile Row, London, on 30 January 1969. Five weeks later, engineer Glyn Johns, whom Lewisohn describes as Get Back's "uncredited producer", began work assembling an album, given "free rein" as the band "all but washed their hands of the entire project".

Question: what was Preston awarded?
Answer: label billing
Martin's first recording session with the Beatles took place at EMI's Abbey Road Studios in London on 6 June 1962. Martin immediately complained to Epstein about Best's poor drumming and suggested they use a session drummer in his place. Already contemplating Best's dismissal, the Beatles replaced him in mid-August with Ringo Starr, who left Rory Storm and the Hurricanes to join them. A 4 September session at EMI yielded a recording of "Love Me Do" featuring Starr on drums, but a dissatisfied Martin hired drummer Andy White for the band's third session a week later, which produced recordings of "Love Me Do", "Please Please Me" and "P.S. I Love You".Martin initially selected the Starr version of "Love Me Do" for the band's first single, though subsequent re-pressings featured the White version, with Starr on tambourine. Released in early October, "Love Me Do" peaked at number seventeen on the Record Retailer chart. Their television debut came later that month with a live performance on the regional news programme People and Places. After Martin suggested rerecording "Please Please Me" at a faster tempo, a studio session in late November yielded that recording, of which Martin accurately predicted, "You've just made your first No.1."In December 1962, the Beatles concluded their fifth and final Hamburg residency. By 1963, they had agreed that all four band members would contribute vocals to their albums – including Starr, despite his restricted vocal range, to validate his standing in the group. Lennon and McCartney had established a songwriting partnership, and as the band's success grew, their dominant collaboration limited Harrison's opportunities as a lead vocalist. Epstein, in an effort to maximise the Beatles' commercial potential, encouraged them to adopt a professional approach to performing. Lennon recalled him saying, "Look, if you really want to get in these bigger places, you're going to have to change – stop eating on stage, stop swearing, stop smoking ..." Lennon said: "We used to dress how we liked, on and off stage. He'd tell us that jeans were not particularly smart and could we possibly manage to wear proper trousers, but he didn't want us suddenly looking square. He'd let us have our own sense of individuality."

Question: What chart did Love Me Do hit number 17 on?
Answer: Record Retailer

Question: By whom was Best replaced in August 1862?
Answer: Ringo Starr
On 25 June 1967, the Beatles performed their forthcoming single, "All You Need Is Love", to an estimated 350 million viewers on Our World, the first live global television link. Released a week later, during the Summer of Love, the song was adopted as a flower power anthem. Two months later, the group suffered a loss that threw their career into turmoil. Having been introduced to Maharishi Mahesh Yogi only the previous night in London, on 25 August they travelled to Bangor for his Transcendental Meditation retreat. Two days later, their manager's assistant, Peter Brown, phoned to inform them that Epstein, only thirty-two years old, had died. The coroner ruled the death an accidental carbitol overdose, although it was widely rumoured to be a suicide. Epstein had been in a fragile emotional state, stressed by personal troubles. His death left the group disoriented and fearful about the future. Lennon recalled: "We collapsed. I knew that we were in trouble then. I didn't really have any misconceptions about our ability to do anything other than play music, and I was scared. I thought, 'We've had it now.'"

Question: When did they travel to Bangor?
Answer: 25 August
Released in March 1963, the album initiated a run during which eleven of their twelve studio albums released in the United Kingdom through to 1970 reached number one. The band's third single, "From Me to You", came out in April and was also a chart-topping hit, starting an almost unbroken string of seventeen British number-one singles for the Beatles, including all but one of the eighteen they released over the next six years. Issued in August, the band's fourth single, "She Loves You", achieved the fastest sales of any record in the UK up to that time, selling three-quarters of a million copies in under four weeks. It became their first single to sell a million copies, and remained the biggest-selling record in the UK until 1978.Their commercial success brought increased media exposure, to which the Beatles responded with an irreverent and comical attitude that defied the expectations of pop musicians at the time, inspiring even more interest. The band toured the UK three times in the first half of the year: a four-week tour that began in February, the Beatles' first nationwide, preceded three-week tours in March and May–June. As their popularity spread, a frenzied adulation of the group took hold. Greeted with riotous enthusiasm by screaming fans, the press dubbed the phenomenon "Beatlemania". Although not billed as tour leaders, the Beatles overshadowed American acts Tommy Roe and Chris Montez during the February engagements and assumed top billing "by audience demand", something no British act had previously accomplished while touring with artists from the US. A similar situation arose during their May–June tour with Roy Orbison.

Question: What was the phenomenon given to the greetings the Beatles' received from the Fans?
Answer: Beatlemania
Rubber Soul had marked a major step forward; Revolver, released in August 1966 a week before the Beatles' final tour, marked another. Pitchfork's Scott Plagenhoef identifies it as "the sound of a band growing into supreme confidence" and "redefining what was expected from popular music". Revolver featured sophisticated songwriting, studio experimentation, and a greatly expanded repertoire of musical styles, ranging from innovative classical string arrangements to psychedelic rock. Abandoning the customary group photograph, its cover – designed by Klaus Voormann, a friend of the band since their Hamburg days – "was a stark, arty, black-and-white collage that caricatured the Beatles in a pen-and-ink style beholden to Aubrey Beardsley", in Gould's description. The album was preceded by the single "Paperback Writer", backed by "Rain". Short promotional films were made for both songs; described by cultural historian Saul Austerlitz as "among the first true music videos", they aired on The Ed Sullivan Show and Top of the Pops in June 1966.

Question: In what year were aired the first 2 music videos?
Answer: 1966
The band's earliest influences include Elvis Presley, Carl Perkins, Little Richard and Chuck Berry. During the Beatles' co-residency with Little Richard at the Star-Club in Hamburg, from April to May 1962, he advised them on the proper technique for performing his songs. Of Presley, Lennon said, "Nothing really affected me until I heard Elvis. If there hadn't been Elvis, there would not have been the Beatles."Other early influences include Buddy Holly, Eddie Cochran, Roy Orbison and the Everly Brothers. The Beatles continued to absorb influences long after their initial success, often finding new musical and lyrical avenues by listening to their contemporaries, including Bob Dylan, the Who, Frank Zappa, the Lovin' Spoonful, the Byrds and the Beach Boys, whose 1966 album Pet Sounds amazed and inspired McCartney. Referring to the Beach Boys' creative leader, Martin later stated: "No one made a greater impact on the Beatles than Brian [Wilson]." Ravi Shankar, with whom Harrison studied for six weeks in India in late 1966, had a significant effect on his musical development during the band's later years.

Question: Which notable acts were responsible for inspiring the work of the Beatles'?
Answer: Elvis Presley, Carl Perkins, Little Richard and Chuck Berry

Question: what advice did little richard give the beatles?

Touring internationally in June and July, the Beatles staged 37 shows over 27 days in Denmark, the Netherlands, Hong Kong, Australia and New Zealand. In August and September they returned to the US, with a 30-concert tour of 23 cities. Generating intense interest once again, the month-long tour attracted between 10,000 and 20,000 fans to each 30-minute performance in cities from San Francisco to New York.In August, journalist Al Aronowitz arranged for the Beatles to meet Bob Dylan. Visiting the band in their New York hotel suite, Dylan introduced them to cannabis. Gould points out the musical and cultural significance of this meeting, before which the musicians' respective fanbases were "perceived as inhabiting two separate subcultural worlds": Dylan's audience of "college kids with artistic or intellectual leanings, a dawning political and social idealism, and a mildly bohemian style" contrasted with their fans, "veritable 'teenyboppers' – kids in high school or grade school whose lives were totally wrapped up in the commercialised popular culture of television, radio, pop records, fan magazines, and teen fashion. To many of Dylan's followers in the folk music scene, the Beatles were seen as idolaters, not idealists." Within six months of the meeting, according to Gould, "Lennon would be making records on which he openly imitated Dylan's nasal drone, brittle strum, and introspective vocal persona"; and six months after that, Dylan began performing with a backing band and electric instrumentation, and "dressed in the height of Mod fashion". As a result, Gould continues, the traditional division between folk and rock enthusiasts "nearly evaporated", as the Beatles' fans began to mature in their outlook and Dylan's audience embraced the new, youth-driven pop culture.During the 1964 US tour, the group were confronted with the reality of racial segregation in the country at the time, particularly in the South. When informed that the venue for their 11 September concert, the Gator Bowl in Jacksonville, Florida, was segregated, the Beatles said they would refuse to perform unless the audience was integrated. Lennon stated: "We never play to segregated audiences and we aren't going to start now ... I'd sooner lose our appearance money." City officials relented and agreed to allow an integrated show. The group also cancelled their reservations at the whites-only Hotel George Washington in Jacksonville. Documents reveal that for their subsequent US tours in 1965 and 1966, the Beatles included clauses in contracts stipulating that shows be integrated.

Question: Bob Dylan was responsible for introducing the Beatles to what?
Answer: cannabis
Though the majority of Chileans reside in Chile, significant communities have been established in multiple countries, most noticeably Argentina, United States, Australia and Canada and countries of the European Union.
