Understanding the Statements
Let’s break down each statement to determine whether they are true (T) or false (F):
(i) The boiling point of water decreases at higher altitudes.
- True (T): At higher altitudes, the atmospheric pressure is lower, which causes water to boil at a lower temperature than the standard 100°C (212°F) at sea level.
(ii) Sharks are mammals.
- False (F): Sharks are not mammals; they are classified as fish. Specifically, they belong to a group called cartilaginous fish, which have skeletons made of cartilage instead of bone.
(iii) The Milky Way is the galaxy that contains our solar system.
- True (T): Our solar system is located within the Milky Way galaxy, which is a barred spiral galaxy that contains billions of stars, including our Sun.
(iv) Carrots are a good source of vitamin A.
- True (T): Carrots are indeed a rich source of beta-carotene, which the body converts into vitamin A, essential for good vision and immune function.
Conclusion
Based on the evaluations:
- Statement (i) is true (T)
- Statement (ii) is false (F)
- Statement (iii) is true (T)
- Statement (iv) is true (T)
Thus, the correct option is a) T F T T. This option accurately represents the truth value of each statement presented.
