user: Is the Vex or FIRST robotics competition a better choice for a child in high school?

assistant: Both VEX and FIRST have very strong robotics competitions for the high school level.  If you are a parent choosing between the two, multiple factors need to be taken into consideration.
The first factor is the availability of a robotics program in your area.  While you can form an independent team that is not affiliated with your school or another organization, it will require a significant financial and time investment.  At the high school level teams typically design their robots with CAD software and must machine the parts themselves.  Teams often consist of 20 or more members so that all of the aspects of the competition can be covered, such as creating and assembling the hardware, electrical wiring, systems design, programming and documenting the engineering process.  All of the parts and equipment need to be purchased and maintained, and members put in a lot of hours during the competition season.  Joining a pre-existing team that already has equipment, members and mentors familiar with a program will make it easiest for a child to participate, regardless of which competition the team is a part of.
If both VEX and FIRST programs are available, then it depends on how intense of an experience the child is interested in.  The VEX competition has a lower barrier to entry because it requires smaller robots.  Two pairs of robots compete against each other in a match to see which pair can get more points.  While teams will need to machine some parts and must have skills in electrical and software design, a team can be smaller and still compete effectively.  The FIRST competition involves much larger and more complex robots and challenges.  Two alliances of three robots each compete against each other in a match, with a total of six robots on the field at once.  Teams need to have more members to effectively compete, and participants need more in-depth training on hardware, electrical, system and software design.  There is also a business requirement, where teams have to create a marketing banner, brochure and video for their team to submit as part of the competition.
Whether you choose VEX or FIRST, a child in high school that participates in a well-run robotics program will gain valuable engineering and organizational experience that will serve them well, both on a college application and after graduation.

user: Extract the difference between Gross Disposable income from Disposable Income

assistant: <think>
The list below represents a national accounts derived indicator for a country or territory's gross household disposable income per capita (including social transfers in kind). According to the OECD, 'household disposable income is income available to households such as wages and salaries, income from self-employment and unincorporated enterprises, income from pensions and other social benefits, and income from financial investments (less any payments of tax, social insurance contributions and interest on financial liabilities). 'Gross’ means that depreciation costs are not subtracted.' This indicator also takes account of social transfers in kind 'such as health or education provided for free or at reduced prices by governments and not-for-profit organisations.' The data shown below is published by the OECD and is presented in purchasing power parity (PPP) in order to adjust for price differences between countries.</think>
There is a unique difference between Gross Disposable Income and Household disposable income.  The first being that "gross" indicates the total about amount of income derived from all sources such as wages, investments, self-employment, pensions and social benefits before extracting depreciation costs.  Household disposable income includes all sources of income less social benefits, taxes, insurance, and liabilities such as rent, electricity and other ongoing financial commitments.  What is remaining is defined as household disposable income which is then indexed globally using PPP (purchasing power parity) in order to adjust for price differences in different countries.

user: What is the game called Lacrosse

assistant: Lacrosse is a team sport played with a lacrosse stick and a lacrosse ball. It is the oldest organized sport in North America,[ with its origins with the indigenous people of North America as early as the 12th century.The game was extensively modified by European colonists, reducing the violence, to create its current collegiate and professional form.

Players use the head of the lacrosse stick to carry, pass, catch, and shoot the ball into the goal. The sport has four versions that have different sticks, fields, rules and equipment: field lacrosse, women's lacrosse, box lacrosse and intercrosse. The men's games, field lacrosse (outdoor) and box lacrosse (indoor), are contact sports and all players wear protective gear: helmet, gloves, shoulder pads, and elbow pads. The women's game is played outdoors and does not allow body contact but does allow stick to stick contact.The only protective gear required for women players is eyegear, while goalies wear helmets and protective pads. Both men's and women's field lacrosse have 6v6 versions played on smaller fields, gaining acceptance in multi-sport events. Intercrosse is a mixed-gender non-contact sport played indoors that uses an all-plastic stick and a softer ball.

The modern sport is governed by World Lacrosse and is the only international sport organization to recognize First Nations bands and Native American tribes as sovereign nations.The organization hosts the World Lacrosse Championship for men, the Women's Lacrosse World Cup, the World Indoor Lacrosse Championship for box lacrosse, and the Under-19 World Lacrosse Championships for both men and women. Each is held every four years. Lacrosse at the Summer Olympics has been contested at two editions of the Summer Olympic Games, 1904 and 1908.It was also held as a demonstration event at the 1928, 1932, and 1948 Summer Olympics.
