php - 让 Javascript True/False 测验在 WordPress 网站上运行

Question

我正在为客户将静态 HTML 站点转换为 WordPress。在他们现有的网站上，他们有这个测验 http://www.virginiauranium.com/quiz .我已将所有内容从他们的原始站点复制到 WordPress 安装，但是正如您在回答问题时所看到的那样，在问题 2 之后它会让您回到第一个问题 http://www.virginiauranium.com/wp/quiz/

我完全被这个难住了，希望这里有人能给我一些指导。我将包括所有相关代码。

$questions = array(

        "answer" => "Uranium is found nearly everywhere in small concentrations. Although used primarily as fuel for nuclear power plants, uranium is also used for weights in airplanes, military armor, and various advanced medical procedures and treatments.", 
        "shortanswer" => "true",

        "caption" => "Ore samples from Coles Hill"
    ), array(
        "question" => "It is standard practice to install waste-water treatment plants at uranium mines and mills today.", 
        "answer" => "If Virginia Uranium’s enterprise moves forward, the company will build a wastewater treatment plant at the mine/mill site.  Water used in the mill process will be recycled and re-used in the mill process. Any water used or collected on site will be cleaned to standards set by the Environmental Protection Agency before it is released on site.  The treatment plant will be capable of cleaning water to E.P.A. drinking-water standards.", 
        "shortanswer" => "true",

    ), array(
        "question" => "Tailings are a radioactive waste product from mining.", 
        "answer" => 'Actually, "tailings" is the term for the crushed rock that remains once the uranium has been removed from the ore in the milling process. The uranium is separated out by a heated sodium bicarbonate leach (basically soda water). The ore at Coles Hill is unique from other uranium ores from the Western U.S or Canada in that it does NOT contain significant quantities of heavy metals or sulfides, which could be of environmental concern.  Yes, there is some radioactivity, but is it important to note that the tailings are less radioactive than the naturally occurring rock in the ore deposit.  Industry best practices recommend the addition of a binding agent to the tailings so that they will harden back into solid rock once they are placed into a below-grade tailings containment structure. The addition of a binding agent and the placement below grade remove any risk that the tailings could be swept away in a flood or hurricane and affect water quality.',

    ), array(
        "question" => "A mining operation at Coles Hill would pollute the air for miles.", 
        "answer" => "Water is used in the mining and milling process to keep down the dispersion of dust.  Moreover, Virginia Uranium’s plan to build an underground mine would eliminate dust emissions outside of the Coles Hill property, and tailings, the crushed rock from which the uranium is removed, are stored as a heavy liquid slurry under water.  They are not susceptible to wind dispersion.  While radon gas is associated with uranium, improved ventilation practices have minimized worker exposure to radon gas over the past forty years.  In fact, according to Canadian regulators, many uranium miners in Saskatchewan, Canada, receive more radon exposure in their homes than in the mines.",

        "answer" => "Highly-respected studies confirm that cancer rates of communities living in the vicinity of uranium mining operations are no higher than those of the general population. Dr. John Boice, an epidemiologist from Vanderbilt University’s School of Medicine, studied four populations who lived near uranium mines in the western United States for decades and found no increased rates of cancer.",

    ), array(
        "question" => "The drastic changes in the spot-market price of uranium will subject Virginia Uranium to boom-and-bust cycles.", 
        "answer" => "Most uranium is sold under long-term price contracts between mining companies and utilities such as Dominion Power.  Contracts lasting up to twenty years are conceivable.  Only about 25% of global uranium mine production is sold on the spot market, because it is in the best interest of utilities to ensure a stable supply of uranium to power their reactors. Long-term supply contracts benefit uranium mining companies by ensuring a stable uranium selling price for long periods of time.",

        "answer" => "Virginia Uranium would require approximately 300,000 gallons of water per day, all of which would come from the 3,500-acre Coles Hill site.  That sounds like a lot of water, but it is slightly less than the Town of Chatham, a nearby town of 1,200 residents, uses. It is far less than other industrial operations in the area have used; for example, Dan River Mills’ textile plant in Danville used 8.2 million gallons of water per day.",

This natural uranium produced at uranium mines and mills must go through the three major processing steps of conversion, enrichment, and fuel rod fabrication before it can even be used in the nuclear reactors that power our world.  Commercial-grade uranium fuel for reactors is usually enriched up to 3.5-5% uranium-235.",

        "answer" => "Uranium, a common element, exists in virtually any rock and in seawater in very small concentrations, but companies do not extract uranium from seawater. The process required to do so is far more expensive than the price of uranium, which means that it is not currently possible to profit from such means of uranium production. Likewise, uranium occurs in Virginia outside of Coles Hill, but, as the National Academy of Sciences has written, it is not worth mining at prevailing prices.",

        "answer" => "The Nuclear Regulatory Commission, the federal agency regulating uranium mills and tailings disposal, has designated below-grade disposal as the prime option for tailings disposal.  Tailings disposal cells must have impermeable liners.  They cannot be located in areas at all prone to flooding. In fact, current industry best practices recommend that tailings be returned to the same geologic structure which held the uranium ore for millions of years prior to mining.",

Operations cannot begin before these bonds are posted, and the amount of the bonds is determined by the NRC during the permitting process and reviewed annually.   For example, Pinion Ridge Mill in Colorado is required to post $11 million in bonds and Homestake Grants in New Mexico $33 million.",
