Article: You can safely keep a woolly bear caterpillar in a clear plastic jar, like a mason jar. The jar should have a lid to prevent the caterpillar from escaping. You can also use a cardboard box. You should punch small holes on the lid. You can also use a mesh lid. It's important for the jar to have some air circulation. Your caterpillar will need a twig to build a cocoon. Place a small twig or branch from outside in the caterpillar's jar. Angle the branch in a diagonal fashion, as this will allow the caterpillar to climb onto it when it's ready to build its cocoon. Each day, you will notice the caterpillar has left droppings in the container. These should be cleaned out regularly. You can move the caterpillar out of the container and use a tissue paper to wipe up droppings. Woolly bear caterpillars need a cold environment to thrive. You should keep the container in a secure location outdoors. Something like a garage or shed near your house is a safe place to keep your caterpillar.
Question: What is a summary of what this article is about?
Use the right container. Provide twigs. Clean the container regularly. Keep the container outside.

Problem: Article: Subtract the Budgeted Cost of Work Scheduled (planned value) from the Budgeted Cost of Work Performed (earned value).  SV = BCWP - BCWS or SV = EV - PV A positive Schedule Variance indicates that the project is ahead of schedule. Negative means it is behind. In the example, this would be the earned value of $1,450 minus the planned value of $1,100. This gives $350, a positive result which indicates that the project is ahead of schedule. Divide the Budgeted Cost of Work Performed by the Budgeted Cost of Work Scheduled.  SPI = BCWP / BCWS or SPI = EV/PV If the SPI is greater than 1, the project is ahead of schedule. If it is less than 1, the project is behind schedule. In the example, this would be the earned value of $1,450 divided by the planned value of $1,100, which gives an SPI of 1.32. This result is greater than 1, indicating that the project is ahead of schedule. Subtract the Actual Cost of Work Performed from the Budgeted Cost of Work Performed.  CV = BCWP - ACWP or CV = EV - AC A positive Cost Variance indicates that the project is under budget. In the example, this would be the earned value of $1,450 minus the actual cost of $1,600. This gives -$150. The negative result means that the project is running over budget and the company may be overspending in some area. Divide the Budgeted Cost of Work Performed by the Actual Cost of Work Performed.  CPI = BCWP / ACWP or CPI = EV/AC If the CPI is greater than 1, the project is under budget. If it is less than 1, the project is over budget. For the security company, their earned value of $1,450 divided by the actual cost of $1,600 yields a CPI of 0.91, meaning that the project is over budget. The resulting total is known as the "Budget at Completion" (BAC). This is simply the combined budgeted costs of the two tasks which is $750 (task one) plus $1,750 (task two) for a total of $2,500. There are two different ways to calculate this measurement. You should use the method more appropriate for the specific circumstances of your project.  If the current cost variance is the result of something that occurred that is not likely to continue, then the BCWS for the remainder of the project is likely still valid. Subtract the Cost Variance from the Budget at Completion to get the estimated actual cost: EAC = BAC - CV. In the example, this would be $2,500 - (-$150), which with the negative sign canceling out the subtraction sign, gives $2,500 + $150, or $2,650. If the current cost variance is the result of circumstances that are likely to continue (such as a higher than expected cost of labor), then divide the Budget at Completion by the Cost Performance Index to estimate the total project cost:  EAC = BAC / CPI. In the example this would be $2,500/0.91, which gives about $2,750.
Summary: Calculated the Schedule Variance (SV). Calculate the Schedule Performance Index (SPI). Calculate the Cost Variance (CV). Calculate the Cost Performance Index (CPI). Compute the budgeted cost for the entire project by adding the BCWS or PV for all project tasks. Calculate the Estimate at Completion (EAC).

Depending on your preference, use 1/4 cup (37.5 grams) of dark chocolate or more the next time you make Rice Krispie buns. You could even use dark chocolate for the entire cup (150 grams) if you prefer. Don’t be afraid to use flavored chocolates, too. Mint, raspberry, or caramel chocolates would all add a unique flavor element to your Rice Krispie buns. After the buns are made, melt down 2 to 3 tablespoons (30 to 44 mL) of white chocolate. Put the melted chocolate into a resealable plastic bag, snip off one corner with a pair of scissors, and drizzle it overtop of the treats. If you really love white chocolate, you could always make a batch of Rice Krispie buns entirely out of it instead of milk chocolate. Use the smooth variety, or choose the chunky kind for some added crunch in your next batch of Rice Krispie buns. Simply add 2 to 3 tablespoons (30 to 44 mL) of peanut butter to the chocolate and butter when you’re melting them down, and then assemble the buns as you usually would. If you’re making the buns for a party, make sure no one has a peanut allergy. Cheerios, Lucky Charms, Chex, Cocoa Krispies, Golden Grahams, and plenty of other cereals would make a great base for your next batch of buns. Simply sub out the 4 cups (100 grams) of Rice Krispies for the same amount of an alternate cereal. You could have a bun making party, where everyone brings their cereal of choice to make a batch. Then everyone can swap and try other varieties of the classic Rice Krispie bun. Add anywhere from 1/4 cup (50 grams) to 1/2 cup (100 grams) of your favorite candy, chopped nut, or mini-marshmallows. Put them into the mix when you add the Rice Krispies so they get coated with chocolate and incorporated along with the cereal. Chocolate- or peanut-based candies would go really well with this treat, but don’t be afraid to try out more unconventional add-ins, like gummy worms or Red Hots!

One-sentence summary --
Substitute part of the milk chocolate for dark chocolate. Drizzle the buns with white chocolate for a sweet complementary flavor. Add peanut butter for a delicious flavor combination. Explore different kinds of cereal to create a more unique bun. Mix in candies, nuts, or marshmallows for an extra-special flavor.
