Once you have enabled AI Servo mode and selected the correct focus points (if you want to adjust them from how the camera is currently set up), the only control you need is the shutter button -- just pressing this halfway will enable focus tracking on the focus points that are enabled.
The Social Security Act was enacted August 14, 1935. The Act was drafted during President Franklin D. Roosevelt's first term by the President's Committee on Economic Security, under Frances Perkins, and passed by Congress as part of the New Deal.
In addition to old-age pensions and unemployment insurance, the Social Security Act established a national welfare system. The federal government guaranteed one-third of the total amount spent by states for assistance to needy and dependent children under age 16 (but not their mothers).n addition to old-age pensions and unemployment insurance, the Social Security Act established a national welfare system.
