Article: The term Carnival is traditionally used in areas with a large Catholic presence. However, the Philippines, a predominantly Roman Catholic country, does not celebrate Carnival anymore since the dissolution of the Manila Carnival after 1939, the last carnival in the country. In historically Lutheran countries, the celebration is known as Fastelavn, and in areas with a high concentration of Anglicans and Methodists, pre-Lenten celebrations, along with penitential observances, occur on Shrove Tuesday. In Eastern Orthodox nations, Maslenitsa is celebrated during the last week before Great Lent. In German-speaking Europe and the Netherlands, the Carnival season traditionally opens on 11/11 (often at 11:11 a.m.). This dates back to celebrations before the Advent season or with harvest celebrations of St. Martin's Day.

Question: What is the Carnival celebration known as in Lutheran countries?
Ans: Fastelavn


Here is a question about this article: The most accurate timekeeping devices are atomic clocks, which are accurate to seconds in many millions of years, and are used to calibrate other clocks and timekeeping instruments. Atomic clocks use the frequency of electronic transitions in certain atoms to measure the second. One of the most common atoms used is caesium, most modern atomic clocks probe caesium with microwaves to determine the frequency of these electron vibrations. Since 1967, the International System of Measurements bases its unit of time, the second, on the properties of caesium atoms. SI defines the second as 9,192,631,770 cycles of the radiation that corresponds to the transition between two electron spin energy levels of the ground state of the 133Cs atom.
What is the answer to this question: How long has the International System of Measurements based the second on caesium?
****
So... Since 1967


The problem: Answer a question about this article:
Celtic tribes settled in Switzerland between 1000 to 1500 BC. The Raetians lived in the eastern regions, while the west was occupied by the Helvetii and the Allobrogi settled in the Rhone valley and in Savoy. Among the many substances Celtic tribes mined was salt in areas such as Salzburg in Austria where evidence of the Hallstatt culture was found by a mine manager in the 19th century. By the 6th century BC the La Tène culture was well established in the region, and became known for high quality decorated weapons and jewelry. The Celts were the most widespread of the mountain tribes—they had warriors that were strong, tall and fair skinned skilled with iron weapons, which gave them an advantage in warfare.
Which were the most widespread of the mountain tribes?
****
The answer: The Celts


Problem: Please answer a question about the following article about Bacteria:
Many important biochemical reactions, such as energy generation, use concentration gradients across membranes. The general lack of internal membranes in bacteria means reactions such as electron transport occur across the cell membrane between the cytoplasm and the periplasmic space. However, in many photosynthetic bacteria the plasma membrane is highly folded and fills most of the cell with layers of light-gathering membrane. These light-gathering complexes may even form lipid-enclosed structures called chlorosomes in green sulfur bacteria. Other proteins import nutrients across the cell membrane, or expel undesired molecules from the cytoplasm.
What kind of membrane do bacteria cells are filled with?
A: light-gathering membrane


Question: Read this and answer the question

However, the army was hopeless in battle against the western forces, particularly against the young Mahmud of Ghazni. In the year 1001, soon after Sultan Mahmud came to power and was occupied with the Qarakhanids north of the Hindu Kush, Jaipal attacked Ghazni once more and upon suffering yet another defeat by the powerful Ghaznavid forces, near present-day Peshawar. After the Battle of Peshawar, he committed suicide because his subjects thought he had brought disaster and disgrace to the Shahi dynasty.

In what year was Jaipal again soundly defeated by the Muslims?
Answer:
1001
