Which one of the following National Parks lies completely in the temperate alpine zone?

Explicitly places Manas among features of the Brahmaputra Plain (alongside Kaziranga), implying a lowland/riverine plain location rather than high mountain terrain.

A student can check a map or elevation data for the Brahmaputra Plain/Manas to compare its typical lowland elevations with alpine/temperate elevation bands given below.

Gives explicit altitudinal bands for Himalayan vegetation: subtropical up to ~1525 m, temperate 1525–3650 m, alpine 3650–4575 m.

Compare Manas' elevation (from maps or gazetteers) to these bands to see if it falls within temperate or alpine ranges.

States alpine and sub‑alpine forests occur along the Himalayas at altitudes ~2500–3500 m (and alpine pastures above ~3500 m), giving another set of elevation thresholds for alpine zones.

Use these altitude thresholds against Manas' known elevations to infer whether it could be alpine/temperate.

Describes vertical zonation of the Himalayas: temperate broad‑leaved in Lesser Himalayas, temperate coniferous around 3500 m, alpine pastures around 4500 m, showing alpine is high elevation.

A student can note alpine corresponds to high Himalayan elevations and thus question alpine classification for a park in the Brahmaputra plain.

Defines alpine tundra as 'above the timberline' and notes it occurs at high elevation in the Himalayas, linking alpine to zones above tree growth limits.

Check whether Manas' environment is above timberline or has alpine tundra vegetation to assess the claim.

Identifies Namdapha National Park as being in Arunachal Pradesh (gives location).

A student can check Arunachal's location on a map and compare Namdapha's latitude/topography to typical Himalayan alpine belts to judge likelihood of full alpine coverage.

States the Namdapha flying squirrel's habitat is 'Tropical forest', implying at least part of the park is tropical rather than temperate/alpine.

Combine this habitat note with maps/elevation data of the park to infer that low-elevation tropical zones exist inside Namdapha, so the park cannot be entirely alpine.

Gives altitude thresholds where temperate forests/grasslands give way to alpine vegetation (around >3,600 m).

Compare Namdapha's known elevation range (from topographic maps) to these thresholds to see whether most/all of the park lies above alpine transition elevations.

Describes montane/temperate species and altitudinal bands (e.g., silver firs, junipers between ~3,000–4,000 m), indicating specific elevation belts for temperate/alpine transitions.

Use these elevation bands against Namdapha's elevation profile to estimate what proportion of the park would be temperate or alpine.

Notes 'Moist alpines are found ... on the higher hills near the Myanmar border' — regionally relevant since Arunachal borders Myanmar.

A student could check whether Namdapha includes those higher hill zones near the Myanmar border and whether such alpine scrub is limited to higher pockets rather than the entire park.

Gives explicit vertical zonation bands for the Western Himalayas (sub‑tropical up to 1525 m; temperate 1525–3650 m; alpine 3650–4575 m).

A student could compare Neora Valley's known elevation range (from a map or park facts) to these bands to see if the park falls wholly inside the alpine band or spans lower zones.

States alpine forests occur at altitudes roughly 2500–3500 m and alpine pastures above ~3500 m; gives tree types and elevation transition points.

Use the park's maximum and minimum elevations to judge whether its vegetation/altitudinal spread matches alpine vs temperate zones.

Defines montane wet temperate forests between 1500–3500 m and mentions dry temperate and other montane belts with altitude ranges.

Compare these temperate belt limits with Neora's elevation profile to test whether the park is fully above (alpine) or includes temperate belts.

Gives examples of species and vegetation types occurring between ~2225–4000 m (blue pine/spruce; silver fir, junipers, rhododendrons 3000–4000 m) indicating where temperate transitions to alpine occur.

If Neora contains these species or sits at elevations cited, a student could infer presence of temperate rather than wholly alpine vegetation.

Defines alpine tundra as 'above the timberline' and notes timberline/ alpine occurrence varies with latitude and elevation in the Himalayas.

A student could locate Neora's latitude and elevation to estimate timberline there and determine if the park lies above (alpine tundra) or below (temperate/treed) it.
