Read the following passage and choose the correct answer to each of the questions.

- Birds that feed in flocks commonly retire together into roosts. The reasons for roosting communally are not always obvious, but there are some likely benefits. In winter especially, it is important for birds to keep warm at night and conserve precious food reserves. One way to do this is to find a sheltered roost. Solitary roosters shelter in         dense vegetation or enter a cavity – horned larks dig holes in the ground and ptarmigan burrow into snow banks – but the effect of sheltering is magnified by several birds huddling together in the roosts, as wrens, swifts, brown creepers, bluebirds, and anis do. Body contact reduces the surface area exposed to the cold air, so the birds keep each other warm. Two kinglets huddling together were found to reduce their heat losses by a quarter and three together saved a third of their heat.

The second possible benefit of communal roosts is that they act as ^"information centers.^" During the day, parties of birds will have spread out to forage over a very large area. When they return in the evening some will have fed well, but others may have found little to eat. Some investigators have observed that when the birds set outagain next morning, those birds that did not feed well on the previous day appear to follow those that did. The behavior of common and lesser kestrels may illustrate different feeding behaviors of similar birds with different roosting habits. The common kestrel hunts vertebrate animals in a small, familiar hunting ground, whereas the very similar lesser kestrel feeds on insects over a large area. The common kestrel roosts andhunts alone, but the lesser kestrel roosts and hunts in flocks, possibly so one bird can learn from others where to find insect swarms.

Finally, there is safety in numbers at communal roosts since there will always be a few birds awake at any given moment to give the alarm. But this increased protection is partially counteracted by the fact that mass roosts attract predators and are especially vulnerable if they are on the ground. Even those in trees can be attacked by birds of prey. The birds on the edge are at greatest risk since predators find it easier to catch small birds perching at the margins of the roost.

Read the following passage and choose the correct answer to each of the questions.

A recent survey of crime statistics shows that we are all more likely to be burgled now than 20 years ago and the police advise everyone to take a few simple precautions to protect their homes.

The first fact is that burglars and other intruders prefer easy opportunities, like a house which is very obviously empty. This is much less of a challenge than an occupied house, and one which is well-protected. A burglar will wonder if it is worth the bother.

There are some general tips on how to avoid your home becoming another crime statistic. Avoid leaving signs that your house is empty. When you have to go out, leave at least one light on as well as a radio or television, and do not leave any curtains wide open. The sight of your latest music centre or computer is enough to tempt any burglar.

Never leave a spare key in a convenient hiding place. The first place a burglar will look is under the doormat or in a flower pot and even somewhere more 'imaginative' could soon be uncovered by the intruder. It is much safer to leave a key with a neighbour you can trust. But if your house is in a quiet, desolate area be aware that this will be a burglar's dream, so deter any potential criminal from approaching your house by fitting security lights to the outside of your house.

But what could happen if, in spite of the aforementioned precautions, a burglar or intruder has decided to target your home. Windows are usually the first point of entry for many intruders. Downstairs windows provide easy access while upstairs windows can be reached with a ladder or by climbing up the drainpipe. Before going to bed you should double-check that all windows and shutters are locked. No matter how small your windows may be, it is surprising what a narrow gap a determined burglar can manage to get through. For extra security, fit window locks to the inside of the window.

What about entry via doors? Your back door and patio doors, which are easily forced open, should have top quality security locks fitted. Even though this is expensive it will be money well spent. Install a burglar alarm if you can afford it as another line of defence against intruders.

A sobering fact is that not all intruders have to break and enter into a property. Why go to the trouble of breaking in if you can just knock and be invited in? Beware of bogus officials or workmen and, particularly if you are elderly, fit a chain and an eye hole so you can scrutinise callers at your leisure. When you do have callers never let anybody into your home unless you are absolutely sure they are genuine. Ask to see an identity card, for example.

If you are in the frightening position of waking in the middle of the night and think you can hear an intruder, then on no account should you approach the intruder. It is far better to telephone the police and wait for help.
