According to the passage, what type of cancer is caused by ultraviolet…

Concept

A question that opens with "According to the passage" is settled inside the text itself. The method is to name the two halves of the relationship the question asks about — the stated cause and the effect it is tied to — then find the one sentence in which the writer joins those two halves, and read that link exactly as written. Outside general knowledge, however sound, cannot extend or replace what the passage states.

Application

1. Name the two halves. The cause given in the question is ultraviolet radiation; the missing half is the type of cancer the writer ties to it.

2. Search the passage for the cause word "ultraviolet". It occurs once, in the second paragraph: "Ultraviolet radiation, invisible to the human eye, is linked to skin cancer."

3. Read the link straight off that sentence. The word the writer places on the other side of "is linked to" is skin cancer, so the type of cancer asked for is of the skin.

4. Match that to the option list: the option naming Skin reproduces the passage’s own wording, so Skin is the answer.

Cross-check

• Liver — no cancer of the liver appears anywhere in the passage; the only internal-damage claim made is that smoke inhaled while smoking "carries substances internally damaging the eyes".

• Bone — the skeleton is never mentioned; the writer’s causal list runs old age, hereditary defect, eye injuries, long exposure to sunrays and smoking, and every one of those is offered as a cause of cataract.

• Blood — no blood disorder is named; the loss of vision the passage describes follows from the lens hardening and turning opaque, not from any circulatory condition.

Watch the trap in the same paragraph: long exposure to sunrays is linked to earlier cataract, which is an eye condition and not a cancer. The one and only cancer named in the whole passage is the skin cancer tied to ultraviolet radiation.

Answer: Skin
