1. Possibility 1: the pick grade is not enough, iron ore needs stone pick, gold mine, diamond mine, emerald mine and Ruby mine all need iron pick
possibility 2: computer card, delay, if delay, ghost animal will [card out] (but this possibility is very low)

2. Studies have shown that the visual contrast sensitivity of video game players is much higher than that of non players. Specifically, players can better distinguish the gray changes of visual modes, and they can easily distinguish different contrast modes. This leads to another problem, that is, can we train people with visual defects to improve their visual perception ability through video games, such as people with amblyopia< Third, video games also have an impact on advanced cognitive ability

for example, game training can significantly improve the mental rotation ability of some people, especially women. In addition, the research on the relationship between games and working memory has made great progress. Franceschini and others in Italy promote the language development and reading ability of children with dyslexia through game training. In the experiment, the children played 80 minutes of action games every day for a total of nine days. Compared with before the experiment, the reading speed of this group of children has been significantly improved, and the accuracy has not decreased. The results of this experiment surpass the traditional reading training for a year, and the researchers found that the increased attention through games can be directly converted into the improvement of reading ability< br />
► The game "Rayman racing rapids" used in Franceschini et al's research

this year, Julia and her colleagues just published an article in the Journal of cognitive neuroscience by measuring the accuracy, reaction time and brain wave activity of video game players and non players in the face of advanced visual cognitive tasks, It is found that the game players react faster and present the neural reaction mechanism related to efficient cognitive activities

in practical application, video games also have unexpected benefits for the elderly with cognitive impairment. In 2008, basak and others used strategic video games to train the elderly's comprehensive abilities of multitasking and cognitive control. In the training, the subjects need to press some buttons to deal with various signs at any time while performing tasks. The game group completed a total of 15 groups of 1.5 hours of training in four to five weeks. As time goes on, the burden of multitasking on cognitive function graally disappears, and the performance of the elderly in the game is getting better and better. Julia said that a large number of behavioral observations were also supported by EEG evidence, such as sitabo enhancement.

3. Here are some ideas
first, remove the carbon deposit and clean the fuel system
the new generation of fuel additive can promote colloid in fuel and carbon deposition in engine. After adding fuel additive for five times, carbon deposition in exhaust pipe is significantly reced, and the filter, exhaust system and fuel system are very clean< Second, enhance the dynamic performance
the nano components in the new generation of fuel additives can adsorb and encapsulate colloids, and proce gas in the combustion chamber under the action of high temperature; Micro explosion;, The second atomization of fuel causes complete combustion and improves engine power. More than 90% of the vehicles use fuel additives for the first time and feel that their power is obviously enhanced. Especially when the car is tired, old, loaded and travelling far away< Third, improve atomization and save fuel
a new generation of fuel additives can directly attack the long-chain carbon bonds in oil molecules by using nano molecular materials, and proce & quot; Micro explosion;, The second atomization of fuel can lead to complete combustion, improve thermal efficiency and rece fuel consumption. The fuel additive can save 10 ~ 18% of the fuel in real vehicle test. Especially for long-distance high-speed driving, it is more economical than usual and can be intuitively felt
four, anti-corrosion, anti rust, lubrication, protect the engine
the new generation of fuel additive is composed of organic nano molecules and more than 10 kinds of materials such as detergency activation factor, anti-oxidation, anti-corrosion and demulsification. Aiming at the research and development of harmful components such as sulfur, gum and carbon deposition in engine oil, the new generation of fuel additives also have the functions of anti-oxidation, cleaning, dispersion, demulsification, anti-corrosion and lubrication< 5. Rece noise, wear and prolong engine life
the excessive noise of the engine is not only e to the poor sealing performance of the car, but also e to impurities such as carbon deposition and oil sludge inside the engine, which accelerate the wear of the engine. In the new generation of fuel additives, cleaning, anti-oxidation, lubrication and other functions can greatly improve this phenomenon. The removal of carbon deposition and gum can significantly rece engine wear, thus recing engine noise and extending engine service life< 6. Eliminate black smoke and rece emissions
e to poor atomization and incomplete combustion of oil procts, a large amount of black smoke is formed. Fuel additives can effectively rece the combustion activation energy and improve the atomization efficiency, so that the non combustible gum in the oil can be fully burned, so as to eliminate black smoke and rece emissions. After five times of continuous addition, the black smoke can be significantly reced or even completely eliminated.
