Problem: Please answer a question about the following article about Norfolk Island:
The Norfolk Island Legislative Assembly decided to hold a referendum on the proposal. On 8 May 2015, voters were asked if Norfolk Islanders should freely determine their political status and their economic, social and cultural development, and to "be consulted at referendum or plebiscite on the future model of governance for Norfolk Island before such changes are acted upon by the Australian parliament". 68% out of 912 voters voted in favour. The Norfolk Island Chief Minister, Lisle Snell, said that "the referendum results blow a hole in Canberra's assertion that the reforms introduced before the Australian Parliament that propose abolishing the Legislative Assembly and Norfolk Island Parliament were overwhelmingly supported by the people of Norfolk Island".
What percentage of Norfolk Island residents voted in favor of self-governance?
A: 68%
Problem: Please answer a question about the following article about Renewable energy commercialization:
Similarly, in the United States, the independent National Research Council has noted that "sufficient domestic renewable resources exist to allow renewable electricity to play a significant role in future electricity generation and thus help confront issues related to climate change, energy security, and the escalation of energy costs Renewable energy is an attractive option because renewable resources available in the United States, taken collectively, can supply significantly greater amounts of electricity than the total current or projected domestic demand." .
Sufficient domestic reneewable resources exist for what reason?
A: to allow renewable electricity to play a significant role in future electricity generation
Problem: Please answer a question about the following article about Cotton:
In Iran (Persia), the history of cotton dates back to the Achaemenid era (5th century BC); however, there are few sources about the planting of cotton in pre-Islamic Iran. The planting of cotton was common in Merv, Ray and Pars of Iran. In Persian poets' poems, especially Ferdowsi's Shahname, there are references to cotton ("panbe" in Persian). Marco Polo (13th century) refers to the major products of Persia, including cotton. John Chardin, a French traveler of the 17th century who visited the Safavid Persia, spoke approvingly of the vast cotton farms of Persia.
What 13th century explorer saw cotton in Persia?
A: Marco Polo
Problem: Please answer a question about the following article about Antenna (radio):
An antenna transmits and receives radio waves with a particular polarization which can be reoriented by tilting the axis of the antenna in many (but not all) cases. The physical size of an antenna is often a practical issue, particularly at lower frequencies (longer wavelengths). Highly directional antennas need to be significantly larger than the wavelength. Resonant antennas usually use a linear conductor (or element), or pair of such elements, each of which is about a quarter of the wavelength in length (an odd multiple of quarter wavelengths will also be resonant). Antennas that are required to be small compared to the wavelength sacrifice efficiency and cannot be very directional. Fortunately at higher frequencies (UHF, microwaves) trading off performance to obtain a smaller physical size is usually not required.
How can this be adjusted more easily than changing antenna types?
A:
tilting the axis
