The Logic: The "Immune Rejection" Process
The sentence describes what happens during an organ or tissue graft.
1. Blank (i): B. suppressed
- Why? To prevent the body from rejecting a graft, doctors must "quiet down" the immune system. If the immune system is NOT effectively suppressed (kept under control), it will react to the "foreign" tissue.
- A. primed and C. activated mean to prepare or start the immune system, which is the opposite of what you want during a graft.
2. Blank (ii): E. proliferation
- Why? When the immune system detects an "other" (the graft), it begins to produce more white blood cells to fight it. Proliferation means a rapid increase in numbers.
- D. reduction (decrease) and F. stasis (standing still/no change) contradict the idea of an active immune response.
3. Blank (iii): I. attack
- Why? This is the final stage of rejection. Once the lymphocytes are produced, they move toward the "foreign tissue" to destroy it. Attack is the only word that fits the context of "distinguishing self from other" to eliminate the "other."
- G. stimulate and H. regenerate would imply the immune system is helping the new tissue grow, which contradicts the "foreign" warning at the start.
Final Completed Sentence
The immune system is capable of distinguishing self from other at the cellular level. After grafting, unless the immune system is effectively (i) suppressed, there is a (ii) proliferation of lymphocytes in the lymph glands; the newly produced lymphocytes then move in to (iii) attack the foreign tissue.
