Introduction:
Basket weaving, pottery, and other handicrafts are examples of traditional crafts that have been practiced for centuries. These crafts are often produced on a small scale and are typically made by individual artisans or small groups of artisans. They are considered to be part of the cottage industry.
Explanation:
Cottage industries are small-scale, decentralized manufacturing businesses that are typically run from the homes of the workers. These industries often rely on manual labor and traditional techniques to produce handmade goods. Basket weaving, pottery, and other handicrafts are perfect examples of cottage industries because:
1. Handmade production: These crafts are typically made by hand using traditional methods and techniques. Each piece is unique and reflects the skill and creativity of the artisan.
2. Small-scale production: Basket weaving, pottery, and other handicrafts are usually produced in small quantities. The production process is often labor-intensive and time-consuming, making it difficult to scale up production.
3. Local sourcing of materials: Artisans often source their materials locally, such as using locally grown fibers for basket weaving or clay from nearby sources for pottery. This not only supports local economies but also adds uniqueness to the products.
4. Artistic expression: Handicrafts are often regarded as an art form, allowing artisans to express their creativity and cultural heritage through their work. These crafts carry a sense of tradition and are deeply rooted in local culture.
5. Market demand: Handicrafts have a niche market, with consumers appreciating the authenticity and uniqueness of these products. They are often sought after as decorative items or as gifts.
Conclusion:
Basket weaving, pottery, and other handicrafts are prime examples of cottage industries. They embody the traditional craftsmanship, artistic expression, and cultural heritage of a region. These industries provide opportunities for artisans to showcase their skills and contribute to the local economy while preserving traditional techniques and knowledge.

Lough Neagh, the largest freshwater lake in the British Isles, faces an alarming ecosystem collapse in 2024, marked by the absence of its native fly. Situated in East-central Northern Ireland, covering 392 sq km with a 5,700 sq km catchment area, it serves as a crucial water source, supplying over 40% of Northern Ireland’s drinking water. Known for Europe’s largest wild eel fishery and hosting 100 bird species, it holds cultural and archaeological significance as a jewel in the region.

Zeros of the polynomial means the value of variable such that the equation is equal to zero.Roots of the equation means the value of the variable for which LHS=RHS which basically means that the equation is equal to zero. Hence Zeros and roots are one and the same thing.

5²ⁿ −2²ⁿ is of the form a²ⁿ − b²ⁿ which is divisible by both (a + b) and (a – b).
So, 5²ⁿ − 2²ⁿ is divisible by both 7, 3.

(1). If a triangle has all the angles greater than 60∘, the sum of angles of the triangle will be more than 180∘
Only (2). is correct because if all the angles are equal, triangle will be an equilateral triangle and sum of all the angles of the triangle will be 180∘.

The least number of acute angles that a triangle can have is 2.

As we cannot have more than one right angle or obtuse angle, we have only two or three acute angles in a triangle.

Further, if one angle is acute, sum of other two angles is more than 90⁰ and we cannot have two right angles or obtuse angles.

Let the three consecutive positive integers be n, n+1 and n+2.

Whenever a number is divided by 3, the remainder obtained is either 0,1 or 2.

Therefore, n=3p or 3p+1 or 3p+2, where p is some integer.

If n=3p, then n is divisible by 3.

If n=3p+1, then n+2=3p+1+2=3p+3=3(p+1) is divisible by 3.

If n=3p+2, then n+1=3p+2+1=3p+3=3(p+1) is divisible by 3.

So, we can say that one of the numbers among n,n+1 and n+2 is always divisible by 3 that is:

n(n+1)(n+2) is divisible by 3.

Similarly, whenever a number is divided by 2, the remainder obtained is either 0 or 1.

Therefore, n=2q or 2q+1, where q is some integer.

If n=2q, then n and n+2=2q+2=2(q+1) is divisible by 2.

If n=2q+1, then n+1=2q+1+1=2q+2=2(q+1) is divisible by 2.

So, we can say that one of the numbers among n, n+1 and n+2 is always divisible by 2.

Since, n(n+1)(n+2) is divisible by 2 and 3.

Hence, n(n+1)(n+2) is divisible by 6.

We know that the perimeter of parallelogram ABCD can be written as

Perimeter = AB + BC + CD + DA

We know that opposite sides of parallelogram are equal

AB = CD and BC = DA

By substituting the values

Perimeter = 9.5 + BC + 9.5 + BC

It is given that perimeter = 30 cm

So we get

30 = 19 + 2BC

It can be written as

2BC = 30 – 19

By subtraction

2BC = 11

By division we get

BC = 5.5 cm

Therefore, AB = 9.5 cm, BC = 5.5 cm, CD = 9.5 cm and DA = 5.5 cm.

B=180-(A+C) B=180-53+44 B=180-97 B=83

Hence, option C is correct.

As position of M and N in Eq. alphabets are 13 and 14 respectively.Same position of F and R in Eq. alphabets are 6 and 18 respectively.

By using the symbols in the table given below, we can draw the following family tree:

Clearly, C is the grandchild of A.

Hence, ‘Grandchild’ is the correct answer.

From the common explanation, we get R sits exactly opposite to U.
Hence, Option C is correct.
Final Arrangement:

Common Explanation:
References:
Exactly two persons are sitting between P and Q.
Only one person is sitting between P and U.
Inferences:
From the above references, we get two different cases:

References:
S is sitting second to the right of R.
Inferences:
From the above reference, we get the following arrangements:

References:
T is not sitting beside S.
Inferences:
So, from this case 2 will be eliminated as T is not sitting beside S.
Hence, we get our final arrangement:

Checking → statement I:

References:

P is married to U.

V is married to R.

Q is the husband of W.

S is the daughter-in-law of W.

Inferences:

From the above references, we can conclude the following:

So, we can’t conclude the relation between X and S.

Thus, statement I alone is not sufficient to answer the question.

Checking → statement II

References:

V is the father of Q.

U is the mother-in-law of Q.

T is the sibling of X.

T is unmarried.

Inferences:

From the above reference, we can conclude the following:

So, we can’t conclude the relation between X and S.

Thus, statement II alone is not sufficient to answer the question.

Checking → statement I and II:

References:

P is married to U.

V is married to R.

Q is the husband of W.

S is the daughter-in-law of W.

V is the father of Q.

U is the mother-in-law of Q.

T is the sibling of X.

T is unmarried.

Inferences:

From the above references, we can conclude the following:

So, we can conclude that X is the husband of S.

Thus, statement I and II together is sufficient to answer the question.

Hence, option D is correct.

The pattern followed here is;

15 is the wrong term that doesn't follow the pattern here.

There should be 12.5 in place of 15.

Hence, "15" is the correct answer.
