Which of the following showed the greatest uniformity in Indus Civilization settlement?
The greatest uniformity in the Indus Valley Civilization is observed in the layout of towns, streets, and drainage systems. Major sites like Harappa and Mohenjodaro were typically divided into a citadel on a higher western mound and a lower town on the eastern side.
Dholavira is considered the most recently discovered major site of the Indus Valley Civilization. Located in the Kutch district of Gujarat, India, it was first identified by archaeologist J.P. Joshi during the 1967-68 period.

Which diagnostic marker is used to monitor for recurrence of 'Colorectal Cancer' after surgery?
CEA is not sensitive enough for initial screening, but it is highly useful for monitoring treatment response and detecting early recurrence in patients previously diagnosed with colorectal cancer.

Which laboratory test is most useful for diagnosing 'Primary Hyperparathyroidism'?
In primary hyperparathyroidism, the parathyroid gland secretes too much PTH regardless of calcium levels. This leads to elevated serum calcium, which should normally suppress PTH production.

A 'Positive Pathergy Test' is a diagnostic criterion for which systemic disease?
The pathergy test involves pricking the skin with a sterile needle. If a small bump or pustule forms within 48 hours, it indicates skin hyperreactivity, which is characteristic of Behçet's disease.

Which diagnostic test uses a radioactive tracer to detect 'hot' or 'cold' nodules in the thyroid?
A thyroid scan helps determine the function of a nodule. 'Cold' nodules do not take up iodine and have a higher risk of being malignant, whereas 'hot' nodules are usually hyperfunctioning and benign.

Which blood test is the most sensitive screening tool for 'Hypothyroidism'?
The pituitary gland is extremely sensitive to small changes in thyroid hormone levels. Therefore, an elevated TSH is the most sensitive and earliest indicator of primary hypothyroidism.

Which imaging modality is the gold standard for diagnosing a 'Subarachnoid Hemorrhage' in the acute phase?
A non-contrast CT scan is the first-line and highly sensitive test for acute subarachnoid hemorrhage, appearing as hyperdense (white) areas in the subarachnoid spaces.

Which condition is characterized by 'currant jelly stools'?
Intussusception occurs when one part of the intestine slides into another. The 'currant jelly' appearance of the stool is caused by a mixture of mucus and blood from the compromised intestinal lining.
