In this task, you will be presented with a context passage, a question about that paragraph, and a possible answer to that question. The task is to check the validity of the answer. Answer with "Yes" or "No".

[EX Q]: An atom is the very smallest particle that still the elements properties. All the atoms of an element are alike. They are also different from the atoms of all other elements. For example, atoms of gold are always the same. It does not matter if they are found in a gold nugget or a gold ring. All gold atoms have the same structure and properties. For example, all gold atoms contain 79 protons. One of golds unique properties is that it is a great conductor of electricity. Gold is a better conductor of electricity than copper. Gold is more rare and expensive than copper. Copper is used in house wiring. Gold is far too expensive. <sep>Are two atoms of different elements the same?<sep>No, atoms of a single element are alike and differ from other elements
[EX A]: Yes

[EX Q]:  Paul put the despised watch away And laid out before him his array Of stones and metals, and when the morning Struck the stones to their best adorning, He chose the brightest, and this new watch Was so light and thin it seemed to catch The sunlight's nothingness, and its gleam.  Topazes ran in a foamy stream Over the cover, the hands were studded With garnets, and seemed red roses, budded.  The face was of crystal, and engraved Upon it the figures flashed and waved With zircons, and beryls, and amethysts.  It took a week to make, and his trysts At night with the Shadow were his alone.  Paul swore not to speak till his task was done.  The night that the jewel was worthy to give.  Paul watched the long hours of daylight live To the faintest streak; then lit his light, And sharp against the wall's pure white The outline of the Shadow started Into form.  His burning-hearted Words so long imprisoned swelled To tumbling speech.  Like one compelled, He told the lady all his love, And holding out the watch above His head, he knelt, imploring some Littlest sign.  The Shadow was dumb. <sep>What were the hands of the watch studded with?<sep>Zircons
[EX A]: No

[EX Q]:  Bin Laden and his aides did not need a very large sum to finance their planned attack on America. The 9/11 plotters eventually spent somewhere between $400,000 and $500,000 to plan and conduct their attack. Consistent with the importance of the project, al Qaeda funded the plotters. KSM provided his operatives with nearly all the money they needed to travel to the United States, train, and live. The plotters' tradecraft was not especially sophisticated, but it was good enough. They moved, stored, and spent their money in ordinary ways, easily defeating the detection mechanisms in place at the time. The origin of the funds remains unknown, although we have a general idea of how al Qaeda financed itself during the period leading up to 9/11. General Financing As we explained in chapter 2,  Bin Laden did not fund al Qaeda through a personal fortune and a network of businesses in Sudan. Instead, al Qaeda relied primarily on a fund-raising network developed over time. The CIA now estimates that it cost al Qaeda about $30 million per year to sustain its activities before 9/11 and that this money was raised almost entirely through donations. For many years, the United States thought  Bin Laden financed al Qaeda's expenses through a vast personal inheritance.  Bin Laden purportedly inherited approximately $300 million when his father died, and was rumored to have had access to these funds to wage jihad while in Sudan and Afghanistan and to secure his leadership position in al Qaeda. In early 2000, the U.S. government discovered a different reality: roughly from 1970 through 1994,  Bin Laden received about $1 million per year-a significant sum, to be sure, but not a $300 million fortune that could be used to fund jihad. Then, as part of a Saudi government crackdown early in the 1990s, the  Bin Laden family was forced to find a buyer for Usama's share of the family company in 1994. The Saudi government subsequently froze the proceeds of the sale. This action had the effect of divesting  Bin Laden of what otherwise might indeed have been a large fortune. Nor were  Bin Laden's assets in Sudan a source of money for al Qaeda. When  Bin Laden lived in Sudan from 1991 to 1996, he owned a number of businesses and other assets. <sep>What kind of a network provided the $30 million al Qaeda used for its activities before 9/11?<sep>Fund-raising
[EX A]:
Yes
