Watch Tower Society publications have claimed that God has used Jehovah's Witnesses (and formerly, the International Bible Students) to declare his will and has provided advance knowledge about Armageddon and the establishment of God's kingdom. Some publications also claimed that God has used Jehovah's Witnesses and the International Bible Students as a modern-day prophet.[note 5] Jehovah's Witnesses' publications have made various predictions about world events they believe were prophesied in the Bible. Failed predictions have led to the alteration or abandonment of some doctrines. Some failed predictions had been presented as "beyond doubt" or "approved by God".

Old English nouns had grammatical gender, a feature absent in modern English, which uses only natural gender. For example, the words sunne ("sun"), mona ("moon") and wif ("woman/wife") were respectively feminine, masculine and neuter; this is reflected, among other things, in the form of the definite article used with these nouns: seo sunne ("the sun"), se mona ("the moon"), t wif ("the woman/wife"). Pronoun usage could reflect either natural or grammatical gender, when those conflicted (as in the case of wif, a neuter noun referring to a female person).

Denial of service attacks are designed to make a machine or network resource unavailable to its intended users. Attackers can deny service to individual victims, such as by deliberately entering a wrong password enough consecutive times to cause the victim account to be locked, or they may overload the capabilities of a machine or network and block all users at once. While a network attack from a single IP address can be blocked by adding a new firewall rule, many forms of Distributed denial of service (DDoS) attacks are possible, where the attack comes from a large number of points and defending is much more difficult. Such attacks can originate from the zombie computers of a botnet, but a range of other techniques are possible including reflection and amplification attacks, where innocent systems are fooled into sending traffic to the victim.
Why is it difficult to defend against DDos?

Traditionally, Switzerland avoids alliances that might entail military, political, or direct economic action and has been neutral since the end of its expansion in 1515. Its policy of neutrality was internationally recognised at the Congress of Vienna in 1815. Only in 2002 did Switzerland become a full member of the United Nations and it was the first state to join it by referendum. Switzerland maintains diplomatic relations with almost all countries and historically has served as an intermediary between other states. Switzerland is not a member of the European Union; the Swiss people have consistently rejected membership since the early 1990s. However, Switzerland does participate in the Schengen Area.
What have the Swiss people continually rejected membership in since the 1990's?
A:
European Union
