Myself Teresa's daughter. => I am Teresa's Daughter.   But in the given options only Son-in-law is available and daughter is not given.   So, Son-in-law is correct.

Answer: A) Dn = log 2 (n+1) Explanation: A complete binary tree is a binary tree where all the levels have maximum number of nodes except possibly the last level.   The depth of complete binary tree of n nodes will be Dn=log 2 (n+1) where Dn is the height or depth of the tree and n is the number of nodes.

Answer: B) 14 Explanation: Given Number series is :   3   4   14   48   576   27648   It follows a pattern that,   3   4   4 x 3 = 12   but not 14   12 x 4 = 48   48 x 12 = 576   576 x 48 = 27648       Hence, the odd one in the given Number Series is 14.

Answer: B) Commercial grain farming Explanation: Monoculture is a typical characteristics of Commercial grain farming. Monoculture is the agricultural practice of producing or growing a single crop, plant, or livestock species, variety, or breed in a field or farming system at a time focussing commercial gains. Monoculture is widely used in both industrial farming and organic farming and has allowed increased efficiency in planting and harvest. Polyculture, where more than one crop is grown in the same space at the same time, is the alternative to monoculture.

Answer: C) Wasshing soda Explanation: Hardness can be removed by adding sodium carbonate (washing soda) or by passing the water through an ion-exchange column.   Hardness in water is caused by dissolved magnesium ions and calcium ions. These can get into the water when it comes into contact with limestone and other rocks that contain calcium compounds. This can happen, for example, when rainwater flows over these rocks on its way to a reservoir.   Hardness in water is of two types. They are : 1. Temporary hardness 2. Permanent hardness   1. Temporary hardness:: Temporary hardness is caused by dissolved calcium hydrogen carbonate. 2. Permanent hardness:: Permanent hardness is caused by dissolved calcium sulfate. Unlike temporary hardness, it is not removed by boiling the water.

Answer: D) Lymphatic system Explanation: Lipoproteins are particles that contain triacylglycerol (TAG), cholesterol, phospholipids and amphipathic proteins called apolipoproteins.   The four major types of lipoproteins are 1. chylomicrons, 2. very low-density lipoprotein (VLDL), 3. low-density lipoprotein (LDL), and 4. high-density lipoprotein (HDL).   Chylomicrons are formed in the endoplasmic reticulum in the absorptive cells (enterocytes) of the small intestine.   The function of these lipoproteins is to deliver energy-rich triacylglycerol (TAG) to cells in the body (pink pathway). TAG is stripped from chylomicrons and VLDL through the action of lipoprotein lipase, an enzyme that is found on the surface of endothelial cells. This enzyme digests the TAG to fatty acids and monoglycerides, which can then diffuse into the cell to be oxidized, or in the case of an adipose cell, to be re-synthesized into TAG and stored in the cell.

Answer: A) TRUE Explanation: Primary care physicians or General practitioners (GP) are the one you go first to get a check up, and if they deem that your problem more severe than they can help you, they will send you to a secondary care physicians like specialists in Cardiologists, Neurologists, Dentists, ...   Hence, the given statement, Primary care physicians are responsible for diagnosis and treatment is TRUE.

Answer: D) Indeterminate Explanation: Indeterminate are those,which mathematics can’t determine. Because we don’t actually know which one is the exact answer for this due to having lots of results for this. Explanation:: Let us think by this analogy that, 0 / 1 = 0 0 / 2 = 0 ………… ……….. we can say 0 / n = 0 from this we can write, 0/0 = 0 Again, another analogy,(from limiting concept of 1/0 = infinity) 1 / 0 = +∞ or -∞ 2 /0 = +∞ or -∞ ……… .……. we can say 0 / 0 = ∞ Again, another analogy, 1 / 1 = 1 2/2 = 1 .…….. ……….. we can say, 0/0 = 1 Now, you see it’s confusing. Every analog is mathematically correct then which one is the right answer for 0/0.  Therefore Mathematics can’t determine this fact. So, 0/0 is indeterminate.
