【简答题】
The following newspaper editorial contains five sentences. Please identify the facts with an "F", opinions with an "O", and the statements of fact and opinion with an "F+O" 1Currently, about half of all three-to five- year-olds in the United States are enrolled in preschool programs, including Head Start, school-based prekindergarden programs, nursery schools and child care. 2 A task force of the Carnegie Corporation has now recommended that almost all children be enrolled in a preschool program at age 3 to improve their prospects for success in school. 3 The task force estimates that 75 percent of the funding for existing early-education services can be provided by families. 4 It is most regrettable that the task force did not provide in the report any suggestion about who should pay the rest of the bill. 5 As a result, while the task force calls for immediate action, its proposal should be seen as a long-term goal that deserves serious study by policymakers and parents.
