Q: Although Brazil is the only Portuguese-speaking nation in South America, it has the largest population, area and economy on the continent. Thus, the South American trade bloc Mercosul uses Portuguese alongside Spanish as its working languages. A Spanish influenced Portuguese dialect is spoken in the northern Uruguayan border area with Brazil. Given the proximity and trading relations between Portuguese speaking Brazil, and its respective Spanish speaking nations, Portuguese is offered as a foreign (or obligatory) second language course at most schools in Uruguay, Argentina, Paraguay, Venezuela and Bolivia.
Can we conclude that is brazil the only country in south america that speaks portuguese?
A: yes

Q: A Taxpayer Identification Number (TIN) is an identifying number used for tax purposes in the United States. It is also known as a Tax Identification Number or Federal Taxpayer Identification Number. A TIN may be assigned by the Social Security Administration or by the Internal Revenue Service (IRS).
Can we conclude that is a taxpayer number the same as a tax id?
A: yes

Q: For symmetry with respect to rotations about a point we can take that point as origin. These rotations form the special orthogonal group SO(m), the group of mm orthogonal matrices with determinant 1. For m = 3 this is the rotation group SO(3).
Can we conclude that is point symmetry a special type of rotational symmetry?
A: yes

Q: Ultimate tensile strength (UTS), often shortened to tensile strength (TS), ultimate strength, or Ftu within equations, is the capacity of a material or structure to withstand loads tending to elongate, as opposed to compressive strength, which withstands loads tending to reduce size. In other words, tensile strength resists tension (being pulled apart), whereas compressive strength resists compression (being pushed together). Ultimate tensile strength is measured by the maximum stress that a material can withstand while being stretched or pulled before breaking. In the study of strength of materials, tensile strength, compressive strength, and shear strength can be analyzed independently.
Can we conclude that is tensile strength the same as breaking strength?
A:
yes
