Answer:
Historical ties and official cooperation
Explanation:
Argentina took in many Nazi war criminals and members of the Nazi party after World War II in part because of the strong presence of German immigration in the South American country. Argentina had received many Germans in the decades prior to the war which helped the country stay close to Germany.
Argentina was also a neutral country during WWII and therefore had an impartial stance toward the warring parties, at least official. In reality, the Argentine government collaborated secretly with the Germans to help escapees leave Europe safely and reach safe haven in the Americas.

Answer:
The correct option is: 2,250,000 kg
Explanation:
Given
: Area A = 1 ha (Hectare) = 10,000 m²
Bulk density = 1.5 Mg/m³ = 1.5 × 1000 kg/m³ = 1500 kg/m³ (∵ 1 Mg=1000 kg)
Depth of soil = 15 cm = 0.15 m (∵ 1 m = 100 cm)
Volume can be calculated by:
Volume = area × Depth = 10,000 m² × 0.15 m = 1500 m³
As we know, density = mass/ volume
Therefore, <u>Mass of soil</u> = Bulk density × volume = 1500 kg/m³ × 1500 m³ = 2,250,000 kg
