Problem: Grape:

Grapes are a type of fruit that grow in clusters of 15 to 300, and can be crimson, black, dark blue, yellow, green, orange, and pink. "White" grapes are actually green in color, and are evolutionarily derived from the purple grape. Mutations in two regulatory genes of white grapes turn off production of anthocyanins, which are responsible for the color of purple grapes. Anthocyanins and other pigment chemicals of the larger family of polyphenols in purple grapes are responsible for the varying shades of purple in red wines. Grapes are typically an ellipsoid shape resembling a prolate spheroid.

What color are white grapes?

Problem: In dominant-party systems, opposition parties are allowed, and there may be even a deeply established democratic tradition, but other parties are widely considered to have no real chance of gaining power. Sometimes, political, social and economic circumstances, and public opinion are the reason for others parties' failure. Sometimes, typically in countries with less of an established democratic tradition, it is possible the dominant party will remain in power by using patronage and sometimes by voting fraud. In the latter case, the definition between dominant and one-party system becomes rather blurred. Examples of dominant party systems include the People's Action Party in Singapore, the African National Congress in South Africa, the Cambodian People's Party in Cambodia, the Liberal Democratic Party in Japan, and the National Liberation Front in Algeria. One-party dominant system also existed in Mexico with the Institutional Revolutionary Party until the 1990s, in the southern United States with the Democratic Party from the late 19th century until the 1970s, in Indonesia with the Golkar from the early 1970s until 1998.
What were two things that the Liberal Democratic Party in Japan used in the 1970's to try and win an election?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
When talking about genome composition, one should distinguish between prokaryotes and eukaryotes as the big differences on contents structure they have. In prokaryotes, most of the genome (8590%) is non-repetitive DNA, which means coding DNA mainly forms it, while non-coding regions only take a small part. On the contrary, eukaryotes have the feature of exon-intron organization of protein coding genes; the variation of repetitive DNA content in eukaryotes is also extremely high. In mammals and plants, the major part of the genome is composed of repetitive DNA.
What area do mammals and plants have differences in?
A: unanswerable

Context and question: It was unclear if Shell would recommence drilling in mid-2013, following the "Kulluk" incident and, in February 2013, the corporation stated that it would "pause" its closely watched drilling project off the Alaskan coast in 2013, and will instead prepare for future exploration. In January 2014, the corporation announced the extension of the suspension of its drilling program in the Arctic, with chief executive van Beurden explaining that the project is "under review" due to both market and internal issues.
In February 2013, Shell Corporation announced that it would pause what?
Answer: its closely watched drilling project off the Alaskan coast

Question: 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.
Is there an answer to this question: Besides China, what other countries saw fighting in this war?

Answer: unanswerable

Problem: Asthma:

Chronic obstructive pulmonary disease can coexist with asthma and can occur as a complication of chronic asthma. After the age of 65 most people with obstructive airway disease will have asthma and COPD. In this setting, COPD can be differentiated by increased airway neutrophils, abnormally increased wall thickness, and increased smooth muscle in the bronchi. However, this level of investigation is not performed due to COPD and asthma sharing similar principles of management: corticosteroids, long acting beta agonists, and smoking cessation. It closely resembles asthma in symptoms, is correlated with more exposure to cigarette smoke, an older age, less symptom reversibility after bronchodilator administration, and decreased likelihood of family history of atopy.

What principles of management are used for increased airway neutrophils and smoking cessation?
