Passage: On 25 June, Iraq launched the second Tawakal ala Allah operation against the Iranians on Majnoon Island. Iraqi commandos used amphibious craft to block the Iranian rear, then used hundreds of tanks with massed conventional and chemical artillery barrages to recapture the island after 8 hours of combat. Saddam appeared live on Iraqi television to "lead" the charge against the Iranians. The majority of the Iranian defenders were killed during the quick assault. The final two Tawakal ala Allah operations took place near al-Amarah and Khaneqan. By 12 July, the Iraqis had captured the city of Dehloran,  inside Iran, along with 2,500 troops and much armour and material, which took four days to transport to Iraq. These losses included more than 570 of the 1,000 remaining Iranian tanks, over 430 armored vehicles, 45 self-propelled artillery, 300 towed artillery pieces, and 320 antiaircraft guns. These figures only included what Iraq could actually put to use; total amount of captured materiel was higher. Since March, the Iraqis claimed to captured 1,298 tanks, 155 infantry fighting vehicles, 512 heavy artillery pieces, 6,196 mortars, 5,550 recoilless rifles and light guns, 8,050 man-portable rocket launchers, 60,694 rifles, 322 pistols, 454 trucks, and 1,600 light vehicles. The Iraqis withdrew from Dehloran soon after, claiming that they had "no desire to conquer Iranian territory." History professor Kaveh Farrokh considered this to be Irans greatest military disaster during the war. Stephen Pelletier, a Journalist, Middle East expert, and Author, noted that "Tawakal ala Allah … resulted in the absolute destruction of Irans military machine.". 
Question: How many more tanks were captured by the Iraqis in March than heavy artillery pieces?

Passage: Salks vaccine was then used in a test called the Francis Field Trial, led by Thomas Francis, Jr., the largest medical experiment in history at that time. The test began with about 4,000 children at Franklin Sherman Elementary School in McLean, Virginia, and eventually involved 1.8 million children, in 44 states from Maine to California. By the conclusion of the study, roughly 440,000 received one or more injections of the vaccine, about 210,000 children received a placebo, consisting of harmless culture media, and 1.2 million children received no vaccination and served as a control group, who would then be observed to see if any contracted polio. The results of the field trial were announced 12 April 1955 (the tenth anniversary of the death of President Franklin D. Roosevelt, whose Franklin D. Roosevelts paralytic illness was generally believed to have been caused by polio). The Salk vaccine had been 60-70% effective against PV1 (poliovirus type 1), over 90% effective against PV2 and PV3, and 94% effective against the development of bulbar polio. Soon after Salks vaccine was licensed in 1955, childrens vaccination campaigns were launched. In the U.S, following a mass immunization campaign promoted by the March of Dimes, the annual number of polio cases fell from 35,000 in 1953 to 5,600 by 1957. By 1961 only 161 cases were recorded in the United States. 
Question: How many states chose not to particpate in the Salks vaccine? 
Answer type: Number
