Read the following paragraph carefully and answer the given questions.
In the year 1963 the two enzymes responsible for restricting the growth of bacteriophage in E. coli were isolated. The first restriction endonuclease - Hind II, whose functioning depended on a specific DNA nucleotide sequence was characterized five years later. It was found that Hind II always cut DNA molecules at a particular point by recognizing a specific sequence of six base pairs. This specific base sequence is known as the recognition sequence for Hind II. Besides Hind II, today we know more than 900 restriction enzymes that have been isolated from over 230 strains of bacteria, each of which recognize different recognition sequences.
DNA fragments can be separated by a technique known as:

The area of region bounded by the curve \(y=\cos x\) and \(x\)-axis between \(x=0\) and \(x=\pi\) is

The function \(Z=\alpha x+\beta y(\alpha, \beta>0)\) corresponds to the objective function of an LPP that needs to be maximized subject to \(x+y \leq 1, x, y \geq 0\).
Then the set of optimal solutions is:
