Input: Article: The Vietnam War was a war fought between 1959 and 1975 on the ground in South Vietnam and bordering areas of Cambodia and Laos (see Secret War) and in the strategic bombing (see Operation Rolling Thunder) of North Vietnam. American advisors came in the late 1950s to help the RVN (Republic of Vietnam) combat Communist insurgents known as "Viet Cong." Major American military involvement began in 1964, after Congress provided President Lyndon B. Johnson with blanket approval for presidential use of force in the Gulf of Tonkin Resolution.

Now answer this question: What congressional declaration gave President Johnson authority to send troops to Vietnam?

Output: the Gulf of Tonkin Resolution

Input: Article: More than two-thirds of inner Boston's modern land area did not exist when the city was founded, but was created via the gradual filling in of the surrounding tidal areas over the centuries, notably with earth from the leveling or lowering of Boston's three original hills (the "Trimountain", after which Tremont Street is named), and with gravel brought by train from Needham to fill the Back Bay. Downtown and its immediate surroundings consists largely of low-rise (often Federal style and Greek Revival) masonry buildings, interspersed with modern highrises, notably in the Financial District, Government Center, and South Boston. Back Bay includes many prominent landmarks, such as the Boston Public Library, Christian Science Center, Copley Square, Newbury Street, and New England's two tallest buildingsthe John Hancock Tower and the Prudential Center. Near the John Hancock Tower is the old John Hancock Building with its prominent illuminated beacon, the color of which forecasts the weather. Smaller commercial areas are interspersed among areas of single-family homes and wooden/brick multi-family row houses. The South End Historic District is the largest surviving contiguous Victorian-era neighborhood in the US. The geography of downtown and South Boston was particularly impacted by the Central Artery/Tunnel Project (known unofficially as the "Big Dig"), which allowed for the removal of the unsightly elevated Central Artery and the incorporation of new green spaces and open areas.

Now answer this question: How much of Inner Bostons land area did not exist when the city was founded?

Output: More than two-thirds

Input: Article: In Latin, papyri from Herculaneum dating before 79 AD (when it was destroyed) have been found that have been written in old Roman cursive, where the early forms of minuscule letters "d", "h" and "r", for example, can already be recognised. According to papyrologist Knut Kleve, "The theory, then, that the lower-case letters have been developed from the fifth century uncials and the ninth century Carolingian minuscules seems to be wrong." Both majuscule and minuscule letters existed, but the difference between the two variants was initially stylistic rather than orthographic and the writing system was still basically unicameral: a given handwritten document could use either one style or the other but these were not mixed. European languages, except for Ancient Greek and Latin, did not make the case distinction before about 1300.[citation needed]

Now answer this question: What was the initial difference between majuscule and minuscule letters?

Output:
stylistic
