Read the passage below carefully and answer the question that follows:
For decades, museum conservators preserving ancient Nok terracotta sculptures relied on destructive sampling to determine internal structural decay. Recently, however, non-invasive X-ray computed tomography (CT) scanning has revolutionized artifact restoration across West Africa. By generating high-resolution three-dimensional cross-sections, conservators can identify hidden fractures and internal moisture pockets without altering the delicate clay matrix. In tests conducted on terracotta heads retrieved from the Jos Plateau, CT imaging revealed that previous restoration attempts using synthetic adhesives had inadvertently trapped humidity, accelerating internal crumbling. Consequently, conservation protocols have shifted toward climate-controlled stabilization rather than chemical patching. While the high cost of advanced diagnostic equipment remains a obstacle for regional institutions, the adoption of non-destructive imaging ensures that invaluable cultural artifacts remain intact for future historical research.
Which of the following statements best expresses the main idea of the passage?
- Non-invasive CT scanning technology has significantly improved the preservation of ancient terracotta artifacts by detecting internal damage safely.Cevap
- BTests conducted on terracotta heads from the Jos Plateau proved that synthetic adhesives trapped humidity and accelerated internal crumbling.
- CMost regional museums across West Africa have stopped restoring artifacts due to the prohibitive cost of modern diagnostic equipment.
- DDestructive sampling continues to be the primary and most reliable method for preserving delicate clay matrix sculptures.
