excavation methods

Correct answer: B. To understand its context

Explanation: In archaeology, provenance and context are essential because an object’s position, layer, and association with nearby remains help explain its function and date. Recording the location allows researchers to connect the object with activities, structures, or other artefacts found there. Option B is correct. Changing colour, increasing price, or making a copy has no role in establishing historical meaning.

Correct answer: D. It may indicate fire or destruction

Explanation: In stratigraphic archaeology, an ash layer is interpreted in relation to its depth, contents, and surrounding structures. It may result from a domestic hearth, industrial activity, accidental fire, warfare, or another destructive event, so context is essential. Option D is correct because ash can indicate burning or destruction. It does not by itself decode scripts, make coins, or change a river’s course.

Correct answer: D. To understand the location of structures and remains

Explanation: The governing concept is spatial recording in archaeological fieldwork. A site map records where walls, houses, drains, burials, tools, and other remains were found, allowing researchers to study their relationships and the organisation of the settlement. Consequently, option D is correct. Mapping is not intended to sell objects, decorate a site, or erase earlier names; it preserves evidence and its context.

Correct answer: A. To record their original position

Explanation: The governing archaeological principle is context documentation. A photograph taken during excavation records an object's position, orientation and relationship to nearby layers or structures before removal. This visual record helps researchers reconstruct how the site was organised and allows later checking of field notes. Option A is correct; beauty, alteration of size and commercial advertising are not scientific excavation purposes.

Correct answer: D. To preserve use marks and residues on them

Explanation: The governing concept is archaeological conservation: cleaning must expose an object without destroying information preserved on its surface. Soil, wear marks, residues, corrosion layers, or microscopic traces may reveal how an object was made and used. Excessive or careless cleaning can remove this evidence, so option D is correct. The goal is not to make artefacts look new, shinier, or commercially attractive, and selling them is unethical and unrelated to study.

Correct answer: A. To record the exact location of finds

Explanation: The governing concept is systematic excavation and spatial recording. Archaeologists divide a site into measured squares or coordinates so that every artefact, layer and structure can be recorded in relation to the others. This preserves archaeological context and allows later comparison and interpretation. Thus option A is correct; decoration, soil improvement and tourist guidance are not the scientific purpose of an excavation grid.

Correct answer: D. To record the location of objects accurately

Explanation: The grid method provides a fixed spatial framework for excavation and recording. Each square can be labelled and documented, allowing archaeologists to note the exact position, depth, and association of artefacts and structures. This preserves archaeological context for later analysis, so option D is correct. Decoration, planting trees, and road construction are unrelated to the method.
