In this task you will be given a passage and a yes/no question based on the passage. You should answer the question using the information from the passage.

Input: Consider Input: passage: Unlike Saint Patrick's Day in Ireland, Saint David's Day is not a national holiday, though there is strong support for it becoming a bank holiday in Wales. In the past, schools have taken a half-day holiday, which continues in some parts of Wales. Saint David's Day is also celebrated in expatriate Welsh communities outside the UK. Cross-party support resulted in the National Assembly for Wales voting unanimously to make Saint David's Day a public holiday in 2000. A poll conducted for Saint David's Day in 2006 found that 87% of people in Wales wanted it to be a bank holiday, with 65% prepared to sacrifice a different bank holiday to achieve this. A petition in 2007 to make Saint David's Day a bank holiday was rejected by the office of the British Prime Minister Tony Blair.
 question: is st david's day a bank holiday in wales?

Input: Consider Input: passage: The number of valence electrons of an element can be determined by the periodic table group (vertical column) in which the element is categorized. With the exception of groups 3--12 (the transition metals), the units digit of the group number identifies how many valence electrons are associated with a neutral atom of an element listed under that particular column.
 question: the number of valence electrons in an atom of an element is equal to the group number?

Output: Yes


Input: Consider Input: passage: The production of milk requires that the cow be in lactation, which is a result of the cow having given birth to a calf. The cycle of insemination, pregnancy, parturition, and lactation is followed by a ``dry'' period of about two months before calving, which allows udder tissue to regenerate. A dry period that falls outside this time frames can result in decreased milk production in subsequent lactation. Dairy operations therefore include both the production of milk and the production of calves. Bull calves are either castrated and raised as steers for beef production or used for veal.
 question: do cows have to be pregnant to get milk?


Output: No
